Question

In looking at the bolded atoms in the answer choices, which pair consists of molecules having the same geometry?

PCl3 and BF3
CH2O and CH3OH
CH2CCl2 and CH2CH2
CO2 and SO2

Answer 1

The choices given were:

PCl3 and BF3

CH2O and CH3OH

CH2CCl2 and CH2CH2

CO2 and SO2

The correct option is CH2CCl2 and CH2CH2 because both of them contains a double bond which is sp^2 hybridized and it shows a trigonal planar geometry.

 

Answer 2

Correct Answer: option C:The pair which consist of molecules having the same geometry is CH2CCI2 and CH2CH2.

Reason: 
Both of the above molecules contain double bonds. They are characterized by  sp^2 hybridization. Also, they possess a trigonal planar geometry. In trigonal planar system, the molecule consist of three equally spaced sp^2 hybrid orbitals, which arranged at angle 120 degree.
