Answer 1

$\sf\huge\bold{Question?}$

Which of the following molecule show pyramidal geometry ?

$a) H_{2}O$

$b) \: BF_{3}$

$c) \: NH_{3}$

$d) \: SF_{6}$

$\sf\huge\bold{Answer:}$

$\fbox{option c) is correct answer.}$

Explanation :

1. $H_{2}O$ has tetrahedral geometry. The resulting molecular shape is bent with an H-O-H angle of 104.5°.
2. The geometry of molecule of $\: BF_{3}$ is 'Trigonal Planar.
3. The molecular geometry of ammonia ($\: NH_{3}$) is trigonal pyramidal or a distorted tetrahedral
4. The hybridization of $\: SF_{6}$ is $\: {sp}^{3}\:{d}^{2}$. $\: SF_{6}$ has octahedral molecular geometry and is non-polar in nature.
