GENERAL KNOWLEDGE

Detailed explanation-1: -Hydrogen and carbon have similar electronegativity values, so the C-H bond is not normally considered a polar covalent bond. Thus ethane, ethylene, and acetylene have nonpolar covalent bonds, and the compounds are nonpolar. Bonds between carbon and other elements such as oxygen and nitrogen are polar.

Detailed explanation-2: -In chemistry, the carbon-hydrogen bond (C−H bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens.

Detailed explanation-3: -Answer and Explanation: A carbon atom and a hydrogen atom form a e) nonpolar covalent bond. When covalent bonds form between two atoms, the electrons shared may be equally distributed between them (nonpolar covalent bonds) or pulled more toward one atom than the other (polar covalent bonds).

Detailed explanation-4: -Question: Explain why and which part of a polar molecule can possibly form hydrogen bonds with other polar molecules while those with nonpolar covalent bonds cannot form such H-bonds.

Detailed explanation-5: -A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen.
