trigonal planar

Detailed explanation-1: -Looking at the PCl3 molecular geometry it is trigonal pyramidal with a bond angle of approx. 103o. The is mainly due to the disproportionate influence or greater repulsion of the phosphorus lone pair which makes it deviate from the ideal angle of 109o.
Detailed explanation-2: -(b) The PCl3 molecule is trigonal pyramidal, while ICl3 is T-shaped.
Detailed explanation-3: -No. In a tetrahedral shape with central atom, the bond angles are about 109.5 degrees.
Detailed explanation-4: -It undergoes sp3 hybridisation which results in tetrahedral electron pair geometry and Trigonal pyramidal molecular geometry.
Detailed explanation-5: -Correct option a PCl3Explanation:PCl3 has sp3-hybridization hence geometry is pyramidal due to presence of one lone pair of electron.
