Chemical Bonding and Molecular Structure

The unique capacity of carbon atoms to bond together to form long chains or rings, is called catenation.

Compounds containing only carbon and hydrogen are called hydrocarbons.

Ethene is an unsaturated hydrocarbon.

this option is correct because halides of Be are covalent in nature because of its small size and hence are soluble in organic solvents like benzene.

this option is correct because when cation exchange resin is first treated with carboxylic acid it becomes capable of donating its hydrogen ions and when comes in contact with the hardness causing cations it exchanges is H⁺ ions with the hardness producing cation.

With the increase in atomic number, the extent of hydration decreases and hence, the ions become less heavy, which leads to the higher mobility.

ANS 2.

This option is correct because Sb₂O₃ is treated with HF to form SbF₃. It is mild Lewis acid and is called as Swart's reagent.

Yes, salt are ionic compounds which are made up cation and anions, so that the product is electrically neutral.

Correct answer. The two alpha-carbon atoms attached to C-N are always trans to each other (on the opposite side of the peptide linkage).

Positive ion is called cation.

Most of the organic compounds form covalent bonds.

Ionic bond is formed by sharing of outermost electron.

Chlorine exist in molecular form.
