Explanation:

Step1: Analyze COCl₂ structure

COCl₂ (phosgene) has a trigonal planar structure around C. C is \( sp^2 \)-hybridized (3 \( sp^2 \) orbitals, 1 unhybridized p orbital). O forms a double bond (1 σ, 1 π) with C, and two Cl form single bonds (σ) with C.

Step2: Identify σ and π bonds

• σ bonds: C(\( sp^2 \)) - Cl(\( p \)) (single bond, σ from \( sp^2 \) of C and p of Cl), C(\( sp^2 \)) - O(\( p \)) (σ part of C=O double bond, from \( sp^2 \) of C and p of O).
• π bond: C(\( p \)) - O(\( p \)) (π part of C=O double bond, unhybridized p orbitals overlap side - by - side).

For the Cl - C bonds (single, σ): use \( \boldsymbol{\sigma: C(sp^2)-Cl(p)} \).
For the C=O π bond: use \( \boldsymbol{\pi: C(p)-O(p)} \).
For the C=O σ bond: use \( \boldsymbol{\sigma: C(sp^2)-O(p)} \).

Answer:

• For the Cl - C bonds (the two single bonds to Cl): \( \sigma: C(sp^2)-Cl(p) \)
• For the C=O π bond (the side - by - side overlapping orbitals): \( \pi: C(p)-O(p) \)
• For the C=O σ bond (the end - on overlapping orbital between C and O): \( \sigma: C(sp^2)-O(p) \)
