  • B NH3
  • C H2O
  • D PH3

Step-by-Step Verified Solution

CH4 - sp3 hybridisation - Bond angle (109o28')

NH3 - sp3 hybridisation - Bond angle ( 107.8o)

H2O - sp3 hybridisation - Bond angle ( 104.5o)

PH3 - No hybridisation - Bond angle ( 90o)

Note : According to DRAGO RULE, lone pair of electrons are in pure s- orbital of the atom P. That is why PH3 has no hybridisation.
