Which statement describes the relative masses of two different particles?

1 answer:

4 0

A neutron has mass 1
A positron has mass 0
A beta particle has mass 0
An alpha particle has mass 4

Following that logic, '2. A beta particle has less mass than a neutron' is the correct answer

1. Show the mechanism for the main product for the monochlorination of 2-methylbutane. List all other products.

Bad White [126]

Answer:

See explanation below

Explanation:

First, we need to understand that the monochlorination of an alkane like this one, involves substitution of one of the atoms of hydrogen of the molecule for an atom of chlorine.

This reaction takes place when the alkane reacts with Cl₂ in presence of light or heat.

When this happens, the first step involves the breaking of the double bond of the chlorine to form the ion Cl⁻.

The next step involves the substraction of the hydrogen of the molecule by the Chlorine. This will leave the alkane with a lone pair available for reaction.

The third step, the alkane with the lone pair of electron substract a chlorine for the beggining and form the mono chlorinated product.

The final step involves forming the remaining products with the remaining reagents there.

In the picture attached you have the mechanism and product for this reaction:
