Question

Arrange priority of CIP sequence of given groups in decreasing order- (I) OH (II) COOH (III) CHOHCH3 (IV) CH2OH (A) I>II>III>IV (B) IV>III>II>I (C) II>III>IV>I (D) IV>I>II>III

According to Cahn-Ingold-Prelong (C I P) sequence, priority order of groups is decided by atomic number or atomic mass of Electronegativity of connecting atom (o > c) conjugative atoms. -OH>-COOH>-CH(O H)CH3>-CH2OH

Q. Arrange priority of $C I P$ sequence of given groups in decreasing order-
(I) $O H$
(II) $COO H$
(III) $C H O H C H_{3}$
(IV) $C H_{2} O H$

$I > II > III > I V$

$I V > III > II > I$

$II > III > I V > I$

$I V > I > II > III$

According to Cahn-Ingold-Prelong $(C I P)$ sequence, priority order of groups is decided by atomic number or atomic mass of Electronegativity of connecting atom $(o > c)$ conjugative atoms.
$- O H > - COO H > - C H (O H) C H_{3} > - C H_{2} O H$
