  • question_answer 90)   Group the following as linear and non-linear molecules. \[{{H}_{2}}O,HOCl,BeC{{l}_{2}},C{{l}_{2}}O\]                

    Answer:

      Linear molecules \[HOCl,BeC{{l}_{2}}\] \[Ci{{O}^{-}}\] ion has linear shape. Linear shape results from\[s{{p}^{3}}\]- hybridisation of Cl-atom. Three positions are occupied by lone pairs and one position by oxygen. \[\,_{\centerdot }^{\centerdot }\underset{\centerdot \centerdot }{\overset{\centerdot \centerdot }{\mathop{Cl}}}\,-\underset{\centerdot \centerdot }{\overset{\centerdot \centerdot }{\mathop{O_{\times }^{\centerdot }}}}\,H\] \[BeC{{l}_{2}}\]has linear shape. Linear shape results from sp-hybridization of Be-atom. Cl-Be-Cl Non-linear molecules: \[{{H}_{2}}O,C{{l}_{2}}O\] \[{{H}_{2}}O\]has V-shaped structure. It results from \[s{{p}^{3}}\] -hybridisation of O -atom.     \[C{{l}_{2}}O\] has V-shaped structure. The oxygen atom undergoes \[s{{p}^{3}}\] -hybridisation.
