Answer:
c. 3
Explanation:
Dicholorination of tertiary alkane ( i.e. isobutane) is a halogenation reaction which makes it possible to replace the alkyl functional group with halogenated chlorine.
When Isobutane is subjected to free radicals chlorination, three distinct dichlorination can be formed.
The mechanism of the formation of these products can be seen in the image attached below.
Aluminum is malleable and conducts Electricity
Answer:
Boron family.
Explanation:
Group 13 is called boron family.
It consist of five members boron, aluminum, gallium, indium and thallium.
Boron is semi metal while other members are metals.
Boron hydrates are used to make organic compounds.
Al is soft metal and aluminum oxides are widely used as thermal insulator.
Aluminum sulfate is also very important commercial compound used in sizing paper.
Gallium is also very important element of this group. It form gallium arsenide which is used to convert the light into electricity.
Indium is malleable soft metal which is used in optical instruments.
Thallium is highly toxic and for the long period of time it as used as insect killing poison.
