n e2 reaction.

Answer:
See explanation below
Explanation:
You forgot to put the picture to do so. In this case, I manage to find one, and I hope is the one you are looking for. If not, then post it again and I'll gladly help you out again.
According to the picture with the answer, we have a cyclohexane with 4 methyl groups there. Two of them are facing towards the molecule with a darker bond. This means that the alkyl bromide, should have a bromine in one of the bonds, and in order to produce an E2 reaction, this bromine should be facing in the opposite direction of the methyl groups which are facing towards. This is because an E2 reaction occurs with the less steric hindrance in the molecule. If the bromine is in the same direction as the methyl group, it will cause a lot more of work to do a reaction, and therefore, an E2 reaction. I will promote instead a E1 or a sustitution product.
Therefore the alkyl bromide should be like the one in the picture 2.

(a)
(b)
(c)
(d)
Answer :
(a) → Halogen
(b) → Transition metal
(c) → Transition metal
(d) → Transition metal
Explanation :
Inert gas : These are the gases which lie in group 18.
Their general electronic configuration is: where n is the outermost shell.
Halogen : These are the elements which lie in group 17.
Their general electronic configuration is: where n is the outermost shell.
An alkali metal : These are the elements which lie in group 1.
Their general electronic configuration is: where n is the outermost shell.
An alkaline earth metal : These are the elements which lie in group 2.
Their general electronic configuration is: where n is the outermost shell.
Transition elements : They are the elements which lie between 's' and 'p' block elements. These are the elements which lie in group 3 to 12. The valence electrons of these elements enter d-orbital.
Their general electronic configuration is: where n is the outermost shell.
(a)
The element having this electronic configuration belongs to the halogen family.
