Question

Which of the following compounds has the lowest boiling point? (A) CH3 CH2 CH2 CH2 CH3 (B) CH3 CH=CH- CH2 CH3 (C) CH3 CH=CH- CH =CH2 (D) CH3 CH2 CH2 CH3

Boiling points of alkanes increase as the number of carbon atom increase or molecular mass increase. Alkenes have high boiling point, so CH3 CH2 CH2 CH3 has the lowest boiling point.

Q. Which of the following compounds has the lowest boiling point?

$C H_{3} C H_{2} C H_{2} C H_{2} C H_{3}$

$C H_{3} C H = C H - C H_{2} C H_{3}$

$C H_{3} C H = C H - C H = C H_{2}$

$C H_{3} C H_{2} C H_{2} C H_{3}$

Boiling points of alkanes increase as the number of carbon atom increase or molecular mass increase. Alkenes have high boiling point, so $C H_{3} C H_{2} C H_{2} C H_{3}$ has the lowest boiling point.

Q. Which of the following compounds has the lowest boiling point?

CH3​CH2​CH2​CH2​CH3​

CH3​CH=CH−CH2​CH3​

CH3​CH=CH−CH=CH2​

CH3​CH2​CH2​CH3​

Boiling points of alkanes increase as the number of carbon atom increase or molecular mass increase. Alkenes have high boiling point, so CH3​CH2​CH2​CH3​ has the lowest boiling point.

$C H_{3} C H_{2} C H_{2} C H_{2} C H_{3}$

$C H_{3} C H = C H - C H_{2} C H_{3}$

$C H_{3} C H = C H - C H = C H_{2}$

$C H_{3} C H_{2} C H_{2} C H_{3}$

Boiling points of alkanes increase as the number of carbon atom increase or molecular mass increase. Alkenes have high boiling point, so $C H_{3} C H_{2} C H_{2} C H_{3}$ has the lowest boiling point.
