**Question:**Which of the following is a good leaving group?**Options:**- A. -NH(CH₃)- B. -CH₃- C. -OH- D. -Br**Explanation:**Good leaving groups are atoms or groups that can easily dissociate from the parent molecule, taking electrons with them. In nucleophilic substitution reactions, stable leaving groups facilitate the reaction. Of the given options, -Br (bromide) is generally considered a good leaving group as it can stabilize the negative charge due to its large size and relatively low electronegativity compared to other options listed.

Leaving group is the atom or group of atom that are removed from the reactants species. Leaving group is itself a stable species and it takes away the bonding electrons with them. Leaving group are mostly anion or neutral atom. Out of -N(CH3)2, -CH3, -OH, -Br the good leaving group is the one that is stabilized by gaing the bonding electrons. -N(CH3)2 it is itself stable in the molecule and it is not stablized after gaining the bonding electrons. -CH3 it is itself stable in the molecule. It form CH3- after gaining the bonding electrons. it is not stabilised after gaining the bonding electrons. -OH it form OH- after gaining the bonding electrons OH- can act as a neucleophile and base and is reactive OH- is not stable. -Br it form Br- after gaining the bonding electrons. It is stable as Br- as bromine has a large size and negative charge is dispersed all over it. So, it can act as a good leaving group. So, correct option is -Br

Reactions of Ethers

Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.

Epoxides

Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.

Williamson Ether Synthesis

An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.
