A balanced chemical equation for preparation of
Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electronegative non-metals. The reactivity and electronegativity of elements decreases down in the group. The F atom is most electronegative in nature, it forms a weak acid with hydrogen.

Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electronegative non-metals. The reactivity and electronegativity of elements decreases down in the group. In other words; in displacement reactions, a more reactive halogen can displace a less reactive halogen to form product. For example, chlorine can displace bromine from its solution but vice-versa is not possible. The reactivity order for halogens is:
(c)

A balanced chemical equation for preparation of
Concept introduction:
Ammonia
A species can act as a base if it accepts hydrogen ion from the solution or donate hydroxide ion.

- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
