150. Which among the following alcohols is most reactive with sodium wire? Ethanol.
Which of the following alcohols is most reactive with sodium wire?
Explanation: Methyl alcohol is also VERY reactive towards sodium metal. Ethyl alcohol reacts more slowly, but is still zippy. Above ethyl alcohol, propyl alcohol and butyl alcohol are very sluggish; and will likely not fully react without heating.
Which of the following is most reactive with sodium?
The compound of the option (C) is most reactive to an aqueous solution of sodium carbonate. When this compound loses a proton, it forms cyclopentadienyl anion which is aromatic and very stable.
Which of the following alcohols is most reactive towards?
Answer. Answer: CH3CH2COOH is most reactive towards esterification as C atom of carboxylic group is stericaly least hindered.
Do alcohols react with sodium metal?
Alcohols react with sodium to form a salt (sodium alkoxide) and hydrogen gas. Due to the low density of the alcohols the sodium sinks. … The reaction proceeds steadily with the evolution of hydrogen gas and leaves a colourless solution of the salt.
Which alcohol is most reactive towards carboxylic acid?
CH3CH2COOH is most reactive towards esterification as C atom of carboxylic group is stericaly least hindered. Greater is the steric hinderance, lower is the reactivity.
Why do alcohols react with metals?
Alcohols are only slightly weaker acids than water, with a K a value of approximately 1 × 10 −16. The reaction of ethanol with sodium metal (a base) produces sodium ethoxide and hydrogen gas. This reaction is identical to the reaction of sodium metal with water. … Likewise, similar reactions occur with potassium metal.
Is potassium more reactive than sodium?
Which is more reactive: sodium (Na) or potassium (K)? Answer: Potassium (K) is more reactive because it is further down in Group 1 than sodium (Na).
What is a highly reactive element?
The halogens, alkali metals, and alkaline earth metals are highly reactive. The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element). … Metals with low reactivity are called noble metals.
Is sodium the most reactive metal?
– As we have already discussed, reactivity of alkali metals tends to increase as you go down the group. Therefore, sodium is less reactive with water than is potassium, likewise with the alkaline metals; calcium is more reactive than magnesium. … – So, out of given metals, Potassium is the most reactive metal.
Which of the following is least reactive towards Lucas reagent?
Therefore, 1∘-alcohol donot react with Lucas reagent at room temperature. The benzyl and allyl alcohols react as rapidly as 3∘ alcohols with Lucas reagent because their carbocations are resonance stabilised and are stable. Thus, CH3CH2CH2OH (1∘ alcohol) is least reactive.
Which of the following alcohols is most basic?
Which of the following is most reactive when treated with Na metal?
The ionization enthalpy of potassium is minimum. It is the most electropositive and most reactive metal.
What is the formula of ethanol?
Can alcohols react with NaOH?
We must always remember that alcohol is a weaker acid than water so therefore alcohols are neutral and cannot react with bases like NaOH and Na2CO3. … Remember alcohol will not react with NaOH since it is neutral.
Can alcohols be used as fuels?
Various alcohols are used as fuel for internal combustion engines. The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
