निम्न में से कौन-सा यौगिक Na से क्रिया करके 4, -5-डाइएथिल-ऑक्टेन बनाएगा?

Options

A. `CH_(3)CH_(2)CH_(2)CH_(2)Br`
B. `CH_(3)CH_(2)CH_(2)- underset(CH_(3))underset(|)(CH)-CH_(2)CH_(2)Br`
C. `CH_(3)CH_(2)CH_(2)CH_(2)-underset(Br)underset(|)(CH)-CH_(3)`
D. `CH_(3)CH_(2)CH_(2)-underset(Br)underset(|)(CH)-CH_(2)CH_(3)`

Answer

D

Explanation

अभिक्रिया, वुर्ट्‌ज-अभिक्रिया है तथा विधि निम्न प्रकार है:
`CH_(3)CH_(2)CH_(2)-underset(CH_(3))underset(|)underset(CH_(2))underset(|)(CH)-Br+2Na+Br -underset(CH_(3))underset(|)underset(CH_(2))underset(|)(CH)-CH_(2)CH_(2)CH_(3) overset("ईथर")to`
`overset(8)CH_(3)overset(7)CH_(2)overset(6)CH_(2)-underset("4,5-डाइएथिलऑक्टेन")(underset(CH_(3))underset(|)underset(CH_(2))underset(|)(overset(5)CH)-underset(CH_(3))underset(|)underset(CH_(2))underset(|)(overset(4)CH))-overset(3)CH_(2)overset(2)CH_(2)overset(1)CH_(3)`
