Ethylenediamine (en) is a bidentate ligand as it can form two bonds with the metal ion.

[Ni(CO)4] is diamagnetic because all electrons are paired in the presence of the strong field ligand CO.

[Co(NH3)6]3+ has unpaired electrons and is therefore paramagnetic.

Sodium (Na) can act as a reducing agent as it readily donates electrons.

KMnO4 is a strong oxidizing agent due to the presence of Mn in a high oxidation state.

C3H6O (acetone) is a ketone, characterized by the carbonyl group (C=O) between two carbon atoms.

Tollen's reagent can oxidize aldehydes but not ketones. Acetone is a ketone and will not react.

Decarboxylation of a carboxylic acid typically yields an alkane.

Decarboxylation of sodium acetate yields methane.

2-bromobutane can undergo elimination to form both 1-butene and 2-butene.

Ester is formed by the reaction of a carboxylic acid with an alcohol in an esterification reaction.

All of the listed compounds can be formed by the esterification of acetic acid with the respective alcohols.

The reaction of an aldehyde with a Grignard reagent forms a primary alcohol after hydrolysis.

2-butanol can be oxidized to form a ketone, specifically butanone.

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

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.

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).
