Each of the following is a noncovalent interaction EXCEPT . a) Hydrogen bond b) Carbon-hydrogen bond c) Van der Waals d) Interaction Dipole-dipole

CARBON-HYDROGEN BOND

Explanation:

The non-covalent interactions in the options are the hydrogen bond, the Van der Waal's bond, the dipole-dipole interaction. The odd one out of the options is the carbon - hydrogen bond.

The carbon-hydrogen bond is a covalent bond involving carbon and hydrogen atoms in which carbon shares its outer valence electrons with up to four hydrogen atoms either forming a complete shell with single bonds or complete shells with double or triple bonds. The type of bonding is found in hydrocarbons and other organic compounds. For example the alkanes, alkenes, alkynes and aromatic hydrocarbons.

The non- covalent bonds are the bonds that bind macro-molecules and do not involve the sharing of pairs of electrons. They are much more weaker than covalent bonds and are very important in the formation of proteins and nucleic acids. This type of bonding includes the electrostatic interactions, hydrogen bonds, hydrophobic bonds, Van der Waal's interactions. The different types of the non-covalent bonds differ in geometry, strength and specificity.

So therefore, carbon-hydrogen bond is the odd one of the non-covalent interactions listed in the options.

the answer is true. hope it .
