Which one of the following substances is more likely to dissolve in CCl 4? CBr4 HBr HCl CH3CH2OH NaCl

CBr4

Explanation:As a general solubility rule: 'like dissolves like'

that is more polar compounds can easily dissolve in polar solvents while non-polar compound can easily dissolve in non polar solvents.

Carbon tetracholride, CCl4, is a non polar solvent and CBr4 is also non polar hence it dissolves easily in ccl4.

While the rest of the compounds mentioned above are polar in nature hence they wont dissolve easily in ccl4.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
