The compound whose formula is written below is a major component of a soft fatty substance:

(a) State the change that would be observed in the physical state of the fatty substance if hydrogen were bubbled through it for long time in the presence of finely divided nickel at about 180\(^o\)C

(c) Determine the amount (in mole) of hydrogen that would be consumed if one mole of the component reacted completely with hydrogen.

(c) State the product of the reaction of the fatty substance with hot concentrated sodium hydroxide solution
