Which of the following has highest bond dissociation enthalpy?

The chlorine atom has the lowest size among all hence it will have the highest bond dissociation enthalpy.

Which has more bond angle NF3 or NCl3?

NCl3 has more bond angle than NF3 because the electronegativity of fluorine is more as compared to chlorine . So,bond pair- bond pair repulsion will be less in case of NF3 as electron cloud shift more towards fluorine due to its more electronegativity than nitrogen which leads to less b.p-b.p repulsion .

Which is the correct order of increasing bond dissociation enthalpy?

The increasing order of bond dissociation enthalpy of the following substances is: F2.

Why is NF3 more stable than NCl3?

– As electronegativity difference between N & F is very big it forms a strong N-F bond and thus stable NF3 molecule. – Electronegativity difference between N & Cl/I is comparatively less and thus N-Cl or N-I bond is relatively weaker. – Less stable NCl3 or NI3 thus is explosive in nature.

Which C-C bond has the highest bond dissociation energy?

Carbon–carbon multiple bonds are generally stronger; the double bond of ethylene and triple bond of acetylene have been determined to have bond dissociation energies of 174 and 230 kcal/mol, respectively.

Which bond should have the highest bond dissociation energy?

Strongest bonds and weakest bonds According to BDE data, the strongest single bonds are Si−F bonds. The BDE for H3Si−F is 152 kcal/mol, almost 50\% stronger than the H3C−F bond (110 kcal/mol). The BDE for F3Si−F is even larger, at 166 kcal/mol.

Why NH3 and NF3 has different bond angles?

NH3: Here N is more electronegative than H so a large electron cloud is crowded over N. This will push the bond pairs N−H away from the central atom. So, the angle of H−N−H will decrease. NF3: Here F is more electronegative than N, so the lone pair cloud over N is scattered into the N−F bonds.

Which has greater bond length NH3 or NF3?

Reason: In NF3, the higher electronegativity of F atoms pull the electrons towards themselves. Therefore, repulsion between bond-pair electrons decreases and the lone-pair-bond-pair repulsion push the bonds closer together. This makes bond angle lesser in NF3 and hence larger in NH3.

Which of the following has highest bond dissociation enthalpy a F2 B Cl2 C Br2 D I2?

F2 is expected to have highest bond dissociation enthalpy but it is Cl2…. the correct decreasing order isCl2>Br2>F2>I2 is is so because fluorine atom has very small size due to which there is a high inter electronic repulsion between two fluorine.

Which is the correct order of bond angle in O3 NO2?

O3 (ozone) shows trigonal planar for the electron pair geometry and and bent the molecular geometry. The one lone electron pair exerts a little extra repulsion on the two bonding oxygen atoms to create a slight compression to a 116 degree bond angle from the ideal of 120 degree.

Which statement is correct about bond angle of NCl3 NF3 and NH3?

So order is NH3>NCl3> NF3(bond angle and repulsion) ..

Why NF3 has less dipole moment than NH3?

The dipole moment of NH3 is higher in comparison to NF3. REASON The F i.e. fluorine is more electronegative than N and pulls the electrons . As the number NF bonds is 3 the 3 F atoms pull the electrons. The resulting electronegative forces decrease the dipole moment.

Why does NCl3 have more bond angle than Nf3?

Answer Wiki. NCl3 has more bond angle than NF3 because the electronegativity of fluorine is more as compared to chlorine . So,bond pair- bond pair repulsion will be less in case of NF3 as electron cloud shift more towards fluorine due to its more electronegativity than nitrogen which leads to less b.p-b.p repulsion .

How many lone pairs are present on the central atom of NCl3?

It contains one nitrogen atom at the center and three chlorine atoms spaced evenly around it. One lone pair is present on the central atom of the NCl3 lewis dot structure and three lone pairs on each chlorine atom. 1. Count total valence electron in NCl3

What is the dot structure for nitrogen in NCl3 Lewis?

X represents the bonded pairs of electrons to the central atom. As per the NCl3 lewis dot structure, nitrogen is the central atom that has 3 bonded pairs of electrons and one lone present on it.

What is nitnitrogen trichloride (NCl3)?

Nitrogen trichloride is a very explosive substance that appears like an oily liquid with the chemical formula NCl3. It smells similar to chlorine. It has a dipole moment of 0.6 D that shows it is moderately polar.
