1.	A covalent molecule AB_(3) has trigonal pyramidal structure. The number of lone pair and bonding pair of electrons in the molecule are ...... .
Answer» 2 and 2 3 and 1 1 and 3 0 and 4 Solution :1 and 3 `AB_(3) and AB_(3)` E are the same type ATOM. There are `sigma` type three A - B BOND in it and one nonbonding electron pair on A. Due to this non bonding electron pair and as per the principal of VSEPR three A - B bonds come closer and FORM the pyramidal triangle structure.
