Explanation

• A Neutralization reaction is a specific type of reaction where an acid and a base react to form a salt and water only, with no other products.
• This reaction is characterized by the elimination of acidic and basic properties, resulting in a neutral solution.
• Example: HCl (acid) + NaOH (base) → NaCl (salt) + H2O (water)

Explanation

When an alcohol reacts with an alkyl magnesium halide (Grignard reagent), the product is an alkane.

The Grignard reagent acts as a strong base, removing the acidic hydrogen from the alcohol's hydroxyl group (-OH) and forming a new carbon-hydrogen (C-H) bond, thus creating an alkane.

The other product is a magnesium alkoxide salt. 

Explanation

The aromatization of n-heptane primarily yields toluene.

This process involves the dehydrogenation and cyclization of n-heptane, facilitated by catalysts like Cr2O3/Al2O3 at elevated temperatures, forming a benzene ring with a methyl substituent.
