Question

The number of electrophiles and nucleophiles present in the species given below are respectively.
$BF _{3}, CO _{2}, Me _{3} N , SO _{3}, CH _{3} \overset{+}{C}O , HS ^{-}, NO _{2}^{+}, FeCl _{3}$ $H _{2} O$

• A. 6,3
• B. 3,6
• C. 4,5
• D. 5,4

Answer 1

Answer: (A)

$BF _{3}$ - Electrophile, $CO _{2}$ - Electrophile,

$Me _{3} N $- Nucleophile, $SO _{3}$ - Electrophile,

$CH _{3} CO$ - Electrophile, $HS ^{-}$ - Nucleophile,

$NO _{2}^{+}$- Electrophile, $FeCl _{3}$ - Electrophile,

$H _{2} O$ - Nucleophile,

So, total number of electrophiles $=6$ Total number of nucleophiles $=3$
