Answer #1

For hydrogen bond to be formed, there must be hydrogen attached to either of Nitrogen, Oxygen or fluorine

CH3CH2NH2: hydrogen is attached to Nitrogen. So, hydrogen bond is formed

NH3: hydrogen is attached to Nitrogen. So, hydrogen bond is formed

CH3OH: hydrogen is attached to oxygen. So, hydrogen bond is formed

PF2H: condition not met. So, no hydrogen bond here

HBr: condition not met. So, no hydrogen bond here

NF3: condition not met. So, no hydrogen bond here

H2CO: condition not met. So, no hydrogen bond here

CF3H: condition not met. So, no hydrogen bond here
