State and explain the types of isomerism in alkanes and alkenes with examples
​

Explanation:

Structural isomerism is seen by all alkanes having 4 or more carbon atoms, indicating that there are two or more different structural formulas that you can draw for each molecular formula. The only lawful isomers of C4H10 are n-butane and isobutane. There are three of Pentane, C5H12, while hexane, C6H14, has five.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

the answer is a and have a great day
