The compound with the molecular formula C₂H₆ belongs to which homologous series? MCQ with Answer and Explanation

Explanation:
In both electrolytic and galvanic cells, oxidation occurs at the anode (AN OX). The anode is positive in electrolytic cells, negative in galvanic. Reduction at cathode (RED CAT). Electroplating: object at cathode, dissolution at anode.

Explanation:
Metalloids (B, Si, Ge, As, Sb, Te) are located along the staircase line on the right side of the p-block, dividing metals from non-metals. They exhibit intermediate properties: semiconductors, brittle, can form alloys. They are in groups 13-17. The s-block contains reactive metals. Group 18 contains noble gases. f-block contains lanthanides and actinides.

Explanation:
Bayer's process uses hot NaOH to dissolve alumina from bauxite, leaving behind insoluble impurities (red mud). Alumina is then precipitated. Hall-Héroult is electrolytic reduction of alumina to aluminium.
