The reaction of an alkyl halide with magnesium forms a Grignard reagent, which is a key intermediate in organic synthesis.

Nitrobenzene can be reduced to aniline using reducing agents like Sn/HCl.

Both aldehydes and ketones can be reduced to their corresponding alcohols using sodium borohydride (NaBH4).

Both aldehydes and ketones can be reduced to their corresponding alcohols.

Tollens' reagent can be used to distinguish aldehydes from ketones, as it oxidizes aldehydes but not ketones.

Nitrous acid can be used to distinguish between primary, secondary, and tertiary amines, as it reacts differently with each type.

2-hexene can exist in cis and trans forms due to the presence of a double bond.

3-pentanol has a chiral center and can also have geometric isomers due to the presence of a double bond.

1,3-butadiene can have structural isomers and also exhibit geometric isomerism due to its double bonds.

2-Butene can exhibit geometric isomerism due to the presence of a double bond with different groups attached.

Acetic acid can exist in two forms (keto and enol) and thus exhibits tautomeric isomerism.

2-hexene has a double bond and can have cis and trans configurations.

Acetic acid can exist in keto and enol forms, thus showing tautomeric isomerism.

Acetone can undergo aldol condensation due to the presence of alpha-hydrogens.

2-chloropropane can undergo elimination to form propene, while the others are less favorable for elimination.

Benzene can undergo Friedel-Crafts alkylation, a reaction where an alkyl group is introduced to the aromatic ring.

Chloroethane can undergo nucleophilic substitution due to the presence of a good leaving group (Cl).

2-Butanol can be oxidized to form butanone (a ketone).

Ethylene can undergo addition polymerization to form polyethylene, a common plastic.

Ketones cannot be oxidized further under normal conditions, unlike aldehydes and alcohols.

C2H4COOH (acetic acid) contains the carboxylic acid functional group (-COOH).

Carbon monoxide (CO) contains a coordinate bond between carbon and oxygen.

Carbon dioxide (CO2) contains double bonds between carbon and oxygen.

In PCl5, phosphorus is in its highest oxidation state of +5.

AlCl3 contains aluminum, which is a p-block element.

Silicon dioxide (SiO2) contains silicon, which is a p-block element.

In water (H2O), hydrogen has an oxidation state of +1.

In sodium hydride (NaH), hydrogen has an oxidation state of -1.

Ethane does not have a double bond or any substituents that would allow for geometric isomerism.

C2H4 (ethylene) does not have enough carbon atoms to exhibit isomerism.
