(a) –CH₃, –OH, –H, –Cl (b) –CH₃, –CH₂CH₃, –CH=CH₂, –CH₂OH
(c) –CO₂H, –CH₂OH, –C≡N, –CH₂NH₂ (d) –CH₂CH₃, –C≡CH, –C≡N, –CH₂OCH₃
Options:
Answer:
D
Solution:
(a) First atoms Cl (17) O (8) C (6) H (1) :
Ans. –Cl –OH –CH₃ –H
(b) The first atoms are all C except none; compare the atoms attached to the first carbon : CH₂OH (O, H, H) CH=CH₂ (C, C, H) CH₂CH₃ (C, H, H) CH₃ (H, H, H) :
Ans. –CH₂OH –CH=CH₂ –CH₂CH₃ –CH₃
(c) CO₂H (O, O, O) CH₂OH (O, H, H) C≡N (N, N, N) CH₂NH₂ (N, H, H) :
Ans. –CO₂H –CH₂OH –C≡N –CH₂NH₂
(d) CH₂OCH₃ (O, H, H) C≡N (N, N, N) C≡CH (C, C, C) CH₂CH₃ (C, H, H) :
Ans. –CH₂OCH₃ –C≡N –C≡CH –CH₂CH₃
