Question

Which of the following is an electrophilic reagent?

• A. $H_{2}O$
• B. ${OH}^{-}$
• C. ${NO}_2^{+}$
• D. None

Answer 1

Answer: (A)

$H_{2}O$

Water is an electrophile which has a ability to take in an electron and which is the property of a part of a molecule. For example a positively charged ion having vacancy for an electron in an unfilled orbital.

For example,In water the oxygen atoms withdraw the electrons that they are supposed to be sharing with the hydrogen atoms and so this hydrogen becomes positive. so the water molecule is polar in nature and allows it to bond with more water molecules and also with other molecules.
