Which of the molecules 

 

H2 , HF , CH4 , CH3OH

 

can be involved in hydrogen bonding?

HF , CH₃OH

Step-by-step explanation

Hydrogen bond is a type of vanderwal force which exist between H-atom attacked to high electronegative element like ( F , O, N ) and interact with other high electronegative element ( F. O' N ) Eg:- O X - H . ..... X - N where ( X = F, D, N ) for given molecules : H - H H - H so No -> H-bonding (X ) not F,ON (ti ) HF : - H - F - . . . H -- F N yes - H-bonding high EN highEN ( V ) 1iii) CHA :- H , C - H - - - . CHA No - 4-bonding ( Not F.ON ) (X ) ( iv ) CH, OH : - highEN CH- O - H - -.. 0 - ch 2 + yes - H-bonding H ( V ) highEN
