Achiral compound X has the formula C8H17Br. Y, C8H17Cl, is chiral. X undergoes base-promoted E2 elimination to give a single alk
ene product Z. Under similar conditions Y produces a mixture of alkenes, including Z. Catalytic hydrogenation of Z affords 2-methylheptane. Propose structures for X and Y.
1 answer:
Answer:
1-bromo-6-methylheptane : X
2-chloro-6-methylheptane: Y
Explanation:
A chiral compound is one which has a carbon with all four groups different.
Given:
Compound X is Achiral
Compound Y is chiral
Compound X gives single alkene on elimination : Z
Compound Y gives mixture of alkenes
Z on hydrogenation gives 2-methylheptane.
So the alkene must have carbon chain arrangement similar to 2-methylheptane and so the compound X and Y.
Based on the information the possible compounds are:
1-bromo-6-methylheptane : X
2-chloro-6-methylheptane: Y
The structures are shown in the figure.

Answer:
(a) Utilization
Explanation:
Thermodynamic energy are:
<h2>(1) Kinetic energy:</h2>Kinetic energy is that type of energy of a body which occurs due to the motion of body. Kinetic energy is always positive. In a bound system, the system remains bound as long as the kinetic energy is less than the potential energy due to the interaction of the body.
Potential energy is defined as the energy in which the energy is possessed by a body or a system for doing some work, by virtue of its position above the ground level.
Therefore,
Potential energy = PE = mgh
This potential energy is a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 m s⁻².
<h2>(3) Stored energy:</h2>Stored energy is a Potential energy.
Hence, the only energy which is not a thermodynamic energy is option (a) Utilization energy.
