The strongest ortho-para and strongest meta directing groups are respectively

Question

The strongest ortho-para and strongest meta directing groups are respectively (A) - NO 2 and - NH 2 (B) - CONH 2 and - NH 2 (C) - NH 2 and - NO 2 (D) - NH 2 and CONH 2

Tardigrade Admin · Accepted Answer

- NH 2 ⇒ Strongest o/p directing arrow because of + R nature - NO 2 ⇒ Strongest m directing arrow because of - R nature

Q. The strongest ortho-para and strongest meta directing groups are respectively

$- N O_{2}$ and $- N H_{2}$

$- CON H_{2}$ and $- N H_{2}$

$- N H_{2}$ and $- N O_{2}$

$- N H_{2}$ and $CON H_{2}$

$- N H_{2} \Rightarrow$ Strongest o/p directing $\to$ because of $+ R$ nature
$- N O_{2} \Rightarrow$ Strongest $m$ directing $\to$ because of $- R$ nature

Q. The strongest ortho-para and strongest meta directing groups are respectively

−NO2​ and −NH2​

−CONH2​ and −NH2​

−NH2​ and −NO2​

−NH2​ and CONH2​

−NH2​⇒ Strongest o/p directing → because of +R nature −NO2​⇒ Strongest m directing → because of −R nature

$- N O_{2}$ and $- N H_{2}$

$- CON H_{2}$ and $- N H_{2}$

$- N H_{2}$ and $- N O_{2}$

$- N H_{2}$ and $CON H_{2}$

$- N H_{2} \Rightarrow$ Strongest o/p directing $\to$ because of $+ R$ nature
$- N O_{2} \Rightarrow$ Strongest $m$ directing $\to$ because of $- R$ nature
