Question
The bond angle H - X - H is the greatest in the compound :
Choose an option
Show full solutionCorrect option: A
Correct answer
ACH4
Step-by-step explanation
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.
