**Wed Nov 13, 2019 9:59 pm**Is the answer for a) H3CNH2 and for b) PF in PF3?

I chose H3CNH2 because HCN will have a triple bond, therefore a shorter bond. And for b, I chose PF bond because bond distances increase with atomic size. Since N is a smaller atom than P, I NF3 will have shorter bond distances... Is my reasoning correct?
