On the basis of VSEPR model the angular arrangement of the bonding pairs corresponds to the angular arrangement of the bonded atoms. Then, which of the following is correct regarding bond angle?

A)  \[{{\operatorname{CO}}_{2}}>{{H}_{2}}O>C{{H}_{4}}\]

B)  \[\operatorname{C}{{O}_{2}}>C{{H}_{4}}>{{H}_{2}}O\]

C)  \[\operatorname{C}{{H}_{4}}>C{{O}_{2}}>{{H}_{2}}O\]

D)  \[{{H}_{2}}O>C{{H}_{4}}>C{{O}_{2}}\]

Correct Answer: B

Solution :

Structure and bond angles of\[C{{O}_{2}}\], \[{{H}_{2}}O\] and \[C{{H}_{4}}\] are as follows
