Q. How many electrons are present in the outermost shell of a carbon atom?

1. 4

Q. Oct-1-yne has the same number of hydrogen atoms as of __________.

1. hept-1-ene
2. hex-1-ene
3. pent-1-ene

Q. , the self linking property along with , helps carbon atoms to make large number of chains and rings.

1. Catenation
2. tetravalency
3. Allotropy
4. nuclear charge

Q. Silicon is also tetravalent. But why can’t it form long chain compounds like carbon?

1. Silicon does not form polymers because of its semiconductor nature.
2. Carbon is small in size, so holds the shared electron pair strongly.
3. Carbon compounds are unreactive.
4. Silicon compounds are highly reactive
