See how the carbon chains are numbered Correct the wrong ones.

Which of these chains has the lowest number for the carbon atom carrying the branch?

Assertion : In alcohols, the boiling point decreases with decrease in the branching of the carbon chain. Reason : -There is the increase in van der Waals/ forces between the number of carbon atoms with decrease in the surface area.

Give number in the correct order to the carbon chains given below: C-C-overset(C-C)overset(|)(C)-underset(C-C)underset(|)C-overset(C-C-C-C)overset(|)(C)-C-C-C

Examine the organic compound given below. CH_3-CH_2-overset(CH_3)overset(|)(CH)-CH_2-CH_2-underset(CH_2-CH_3)underset(|)(CH)-CH_2-CH_3 : How many carbons atoms are there in the longest carbon chain?

How many grams of carbon and oxygen are required to get the same number of atoms as in one gram of Helium?

Which one is wrong?
