(c) -C≡N, -COOH, -CH2NH2, -CH2Cl (d) -C(CH3)3, -CH(CH3)2, -CH2CH3, -CH3
Options:
Answer:
D
Solution:
(a) First atoms : Br (35) O (8) C (6) H (1) : -Br -OCH3 -CH3 -H.
(b) -CH2OH is attached to (O, H, H); -CH=CH2 to (C, C, H); -CH2CH3 to (C, H, H); -CH3 to (H, H, H) : -CH2OH -CH=CH2 -CH2CH3 -CH3.
(c) -CH2Cl is attached to (Cl, H, H); -COOH to (O, O, O); -C≡N to (N, N, N); -CH2NH2 to (N, H, H) : -CH2Cl -COOH -C≡N -CH2NH2.
(d) -C(CH3)3 is attached to (C, C, C); -CH(CH3)2 to (C, C, H); -CH2CH3 to (C, H, H); -CH3 to (H, H, H) : -C(CH3)3 -CH(CH3)2 -CH2CH3 -CH3.
