• # question_answer Which of the following species contains three bond pairs and one lone pan- around the central atom? A) $NH_{2}^{-}$B) $PC{{l}_{3}}$C) ${{H}_{2}}O$D) $B{{F}_{3}}$

$PC{{l}_{3}}$has $s{{p}^{3}}-$hybridization and possesses one lone pair on P-atom and three bond pair of electrons \begin{align} & {{(s{{p}^{3}})}^{2}}\,\,\,\,{{(s{{p}^{3}})}^{2}}\,\,\,\,{{(s{{p}^{3}})}^{1}}\,\,\,\,{{(s{{p}^{3}})}^{1}} \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\vdots \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\vdots \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\vdots \\ & \,\,\,\,\,\,\,\,\,\,\,\,3p\,of\,\,\,\,\,\,\,\,\,\,\,3p\,of\,\,\,\,\,\,3p\,of \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Cl\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Cl\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Cl \\ \end{align}
