1.	State the difference in Lewis dot structure. (i) BCl_(3) and BH_(3) "(ii) " BeCl_(2)and BeH_(2)
Answer» Solution :In `BCl_(3)` central ATOM B has incomplete octet . while a has octet In `BH_(3)` central atom B has incomplete octet and H does not possess octet. In `BeCl_(2)` Be has incomplete octet. TWO bonds are these so only 4 ELECTRONS while Cl has octet. In `BeH_(2)`Be and H both does not possess octet. In `BeCl_(2) and BeH_(2)` both Be has same electron but Cl and H has different electron.
