Question

The number of electrophiles and nucleophiles present in the species given below are respectively.
$B{F}_3,C{O}_2,M{e}_{3}N,S{O}_3,C{H}_3\stackrel{+}{C}O,H{S}^{-},N{O}_2^{+},FeC{l}_3$ $H_{2}O$

• A. 6,3
• B. 3,6
• C. 4,5
• D. 5,4

Answer 1

Answer: (A)

$B{F}_3$ - Electrophile, $C{O}_2$ - Electrophile,

$M{e}_{3}N$- Nucleophile, $S{O}_3$ - Electrophile,

$C{H}_{3}CO$ - Electrophile, $H{S}^{-}$ - Nucleophile,

$N{O}_2^{+}$- Electrophile, $FeC{l}_3$ - Electrophile,

$H_{2}O$ - Nucleophile,

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