Out of `CHCl_3, CH_4 and SF_4` the molecules having regular geometry are

Options

A. `CHCl_(3) ` only
B. `CHCl_(3) " and " SF_(4)`
C. `CH_(4) ` only
D. `CH_(4) " and " SF_(4)`

Answer

c

Explanation

Due to absence of lone pair of electrons on carbon
` CH_(4)` has regular tetrahedral geometry . Although
` CHCl_(3)` also does not have lone pairs of electrons on
carbon but due to the presence of three polar C-Cl
bond , and one almost non-polar C-H bond , its
geometry is little distorted from the regular shape .
In contrast , ` SF_(4)` has one lone pair and four bond
pairs , therefore it does not have a regular geometry
Thus , option (C) is correct .
