$H_{2} O, N_{2}, CO, {XeF}_{4}, {NH}_{3}, NO, {CO}_{2}, F_{2}$

Question

The number of molecules from the following which contain only two lone pair of electrons is _____________ H 2 O , N 2 , CO , XeF 4 , NH 3 , NO , CO 2 , F 2

TestHub · Accepted Answer

The lone pair of electrons can be identified by drawing structure of the given moleules as follows,

The number of molecules having only $2$ lone pair of electrons $= 3$

Which are $H_{2} O, N_{2}$ and $CO$ . ${XeF}_{4}$ have $2$ lone pairs on central atom, but we are asked about lone pair in molecule
