Solution


Q.

Total number of nucleophiles from the following is :                        [2025]
1 6  
2 4  
3 5  
4 7  

Ans.

(3)

NH3,PhSH,(CH3)2S,CH2=CH2 and OH- are nucleophiles. (CH3)2C=O is generally considered as electrophilic. The carbonyl carbon carries partial positive charge and is susceptible to attack by nucleophiles. Same is the case with (CH3)2C=NCH3.
