Which molecule is not able to form a co-ordinate bond with another species? A) BH3 B )CH4 C )NH3 D )H2O the answer is B but why cannot it be A as boron is group 3 so all the outer electrons are involved in bonding so no lone pairs therefore no dative covalent bond

Try drawing a dot-and-cross diagram of BH3.
How many outer electrons are there in the boron and how many electrons should there be as a general rule of thumb?
It is also worth noting that for a coordinate bond to form in a reaction, one of your reactants must be a lone pair donor and the other must be a lone pair acceptor.

Thanks lots for the explanation! I as well had no clue why the ans is what it is
