Question:
The angle strain in cyclobutane is
The angle strain in cyclobutane is
Updated On: Apr 2, 2024
- $24^\circ 44'$
- $29^\circ 16'$
- $19^\circ 22'$
- $9^\circ 44'$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
When carbon is bonded to four other atoms, the angle between any pair of bonds $=109^{\circ}, 28'$ (tetrahedral angle) but the ring of cyclobutane is square with four angles of $90^{\circ}$.
So, deviation of the bond angle (angle strain) in
cyclobutane $=109^{\circ} 28'-90^{\circ} / 2 $
$=19^{\circ} 28 \% 2=9^{\circ} 44'$

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
