Question

I started to write about the crystalline latice.. but i think that this is not completley why this phenomenon would occur.

meting point range uould be arund 5. If the melting point of an organic acid is knovti, bietly explain is the melting point will be higher or lower ifor A. the sodi um salt of the organic acid Ihe metting point uould be decreased.

The question states:

5. If the melting point of an organic acid is known, explain if the melting point will be higher or lower for:

a) the sodium salt of the organic acid

b) a non-polar hydrogen compound of similar molecular weight

Answer 1

у м 4. w . dis's (a) Melting point of sodium sult of the Organic acid will be higher . Because more enere the salt will be crystalline in nature. It takes lot of energy to break the crystalline lattice of the salt. Thus melting point of sodium salt of the organic and a will be higher. menolar hydrogen comp

Polar / salts, have positive and negative ends. They are attracted by strong intramoleiular forces of atriation 4 lakes more energy, to separate the molecules from each other. Therefore polar molecules have high melting points.

woud (b) Melting point of non-polare hydrogen comp of similar molecular weight will be lower because the non-polar compounds have weak veun-der Waals forces which are easy to break. Non-polare compounds are held together by weak van der Waals foreres compounds Polar / salts, have positive and negative and and they are attracted by strong -
