B. The periodic law
The periods that make up the periodic table were conceived by Mendeleev in 1869, not Dalton
Explanation:
Both alcoholic group and carboxylic group are polar in nature.
This is because in carboxylic groups are both hydrogen bond acceptor and hydrogen bond donor. Also there is presence of two electronegative oxygen atoms.
Whereas in alcoholic groups also there is hydrogen bonding and there is one electronegative oxygen atom present.
Hence, it makes carboxylic group more polar.
Thus, we can conclude that and both are polar in nature.

False. gases have to greatest freedom of motion
A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms. Since electrons spend more time with the oxygen atom, it carries a partial negative charge.
