1.	The structure of triphenylmethyl cation is given below . This very stable and some of its salts can be stored for months . Explain the cause of high stability of this cation .
Answer» Solution : ` square ` In triphenylmethyl cation, DUE to RESONANCE the positve charge can MOVE at both the o- and p-positions of each benzene ring . [ Six more structures are possible due to resonance in other two benzene rings] ` square ` TOTALLY nine resonance structures are possible for 3 benzene rings . ` square therefore ` Triphenylmethyl cation is HIGHLY stable due to these nine resonance structure .
