What reaction will take place if ethyl alcohol is added to a solution of hcξc: - na+ in liquid ammonia?

Acetylene appear as gas and is unstable and thus kept in presence of other solution such as liquid ammonia.

Ethanol on reacting with ammonia produces ethylamine as follows:

Ethanol again on reacting with ethylamine produces diethylamine  and triethylamine  as follows:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
