Arrange the different parts of the root vertically, from the top to the bottom.

Options:
A Region of elongation â Root hair â Region of maturation â Region of meristematic activity â Root cap
B Region of maturation â Root hair â Region of elongation â Region of meristematic activity â Root cap
C Region of maturation â Region of elongation â Region of meristematic activity â Root cap â Root hair
D Root cap â Region of meristematic activity â Region of elongation â Root hair â Region of maturation

The correct answer is:
Region of maturation → Root hair → Region of elongation → Region of meristematic activity → Root cap

Solution:
The root is covered at the apex by a thimble-like structure called the root cap. It protects the tender apex of the root as it makes its way through the soil. A few millimetres above the root cap is the region of meristematic activity. The cells of this region are very small, thin-walled and with dense protoplasm. They divide repeatedly. The cells proximal to this region undergo rapid elongation and enlargement and are responsible for the growth of the root in length. This region is called the region of elongation. The cells of the elongation zone gradually differentiate and mature. Hence, this zone, proximal to region of elongation, is called the region of maturation. From this region some of the epidermal cells form very fine and delicate, thread-like structures called root hairs. These root hairs absorb water and minerals from the soil.
Vertically, from top to bottom, the order is: Region of maturation â Root hair â Region of elongation â Region of meristematic activity â Root cap

Options:
A Ethanal < Butanone < Propanal < Propanone
B Propanal < Ethanal < Butanone < Propanone
C Butanone < Propanone < Propanal < Ethanal
D Butanone < Propanone < Ethanal < Propanal

The correct answer is:
Butanone < Propanone < Propanal < Ethanal

Solution:
Correct Option is : (C)
Butanone < Propanone < Propanal < Ethanal

Topic: Chemistry, Aldehydes and Ketones, NEET
Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reactions.
Ethanal, Propanal, Propanone, Butanone

Options:
A Butanone < Propanone < Propanal < Ethanal
B Propanone < Butanone < Ethanal > Propanal
C Propanal < Ethanal < Propanone < Butanone
D Ethanal < Propanal < Propanone < Butanone

The correct answer is:
Butanone < Propanone < Propanal < Ethanal

Solution:
The increasing order of their reactivity in nucleophilic addition reactions can be given as
Butanone < Propanone < Propanal < Ethanal.
As reactivity decreases with increase in the size of alkyl group which hinders the incoming nucleophile.
