The -OCH3 group shows +M effect as it donates electrons through resonance.

The –OH group donates electron density through resonance, exhibiting a +M effect.

-NO2 is a strong electron-withdrawing group that decreases electron density on the benzene ring.

Iodobutane can be converted to an alcohol by hydrolysis, while bromobenzene requires a different mechanism due to its aromatic nature.

Iodoethane has the highest boiling point due to the larger size and polarizability of iodine.

Iodoethane is least soluble in water due to its larger size and lower polarity compared to the others.

3-bromopropane is more reactive due to the stability of the tertiary carbocation formed during the reaction.

3-bromopropane is a tertiary haloalkane, which is more reactive towards nucleophilic substitution due to steric hindrance and stability of the carbocation formed.

3-chloropropane is a tertiary haloalkane and will undergo elimination more readily due to the stability of the resulting alkene.

2-bromopropane undergoes elimination readily due to the formation of a stable alkene.

All of the listed haloarenes can undergo nucleophilic substitution under suitable conditions.

Nitrochlorobenzene is most reactive due to the electron-withdrawing nitro group, which stabilizes the negative charge in the intermediate.

Iodobenzene is the most reactive towards nucleophilic substitution due to the weaker C-I bond compared to the other haloarenes.

Cyclobutane is a cyclic compound, while the others are linear alkenes or alkanes.

Methane (CH4) is a gas at room temperature, while the others are liquids.

Polylactic acid (PLA) is a biodegradable polymer derived from renewable resources.

Isopentane is a branched alkane, while the others are straight-chain alkanes.

2-Methylbutane is a branched-chain alkane derived from butane.

Glucose is a simple sugar and a primary carbohydrate.

Alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms.

Cycloalkanes are characterized by their ring structure.

+M effect is characterized by electron donation through resonance, enhancing stability.

Alkanes are saturated hydrocarbons, meaning they contain only single bonds.

Aromatic compounds follow Huckel's rule, which states that they must have (4n + 2) π electrons in a cyclic, planar structure.

Carbohydrates are generally hydrophilic, meaning they are soluble in water.

Cellulose is composed of glucose units linked by β-1,4 glycosidic bonds and is not soluble in water.

Cis-trans isomers have the same connectivity but differ in the spatial arrangement of groups around a double bond.

Cycloalkanes have a ring structure and can be saturated or unsaturated.

Enzymes are highly specific to their substrates, allowing them to catalyze specific biochemical reactions.

Fibrous proteins are typically insoluble in water and serve structural roles in cells and tissues.
