Hexanoic acid, a carboxylic acid, dissolves in 1 M NaOH. Fill in the blank for the missing species:(Structure of Hexanoic acid) + 1M NaOH> …………………………… + …………..water insoluble >. water soluble salt

Hexanoic acid is water insoluble and sodium hexanoate is water soluble

Explanation:

Hexanoic acid is water insoluble because of presence of long 6 membered non polar and hydrophobic hydrocarbon chain.

When hexanoic acid is treated with NaOH, it is converted to an ionic salt sodium hexanoate which is highly soluble in water because of it's ionic nature.

So, the reaction is given as:

         Hexanoic acid + NaOH Sodium hexanoate + water

Reaction in terms of molecular structure has been shown below.
