Best answer: How many alcohols give immediate turbidity?

How many alcohols give immediate turbidity with Lucas reagent?

Lucas reagent is used for distinction between primary, secondary and tertiary alcohols. Tertiary alcohol gives turbidity immediately with Lucas reagent.

How many alcohols will give immediate turbidity?

Correct answer is ‘5’.

Which alcohol will give fastest white turbidity?

– 2-methyl propan-2-ol is tertiary alcohol and as we know that tertiary alcohols show turbidity immediately and they give Lucas test.

How many structural alcohol of formula c5h12o can give instant turbidity?

– There are eight structural isomeric alcohols of pentanol. – Therefore, alcoholic structural isomers having the molecular formula, ${{C}_{5}}{{H}_{11}}OH$ are eight. Therefore, the correct answer is option C.

How many of the following alcohols will give turbidity immediately with HCl and ZnCl2?

The reagent, conc. HCl and anhydrous ZnCl2 is Lucas reagent, which is used to distinguish between 1°, 2° and 3° alcohols. 3° alcohol + Lucas reagent → Immediate turbidity.

Which of the following gives immediate turbidity on reaction with HCl and ZnCl2?

butan-2-ol.

How many of the structurally isomeric pentyl alcohol will produce immediate turbidity in Lucas test?

How many of the structurally isomeric pentyl alcohols will produce immediate turbidity in Lucas test? Only 3∘ alcohols immediately give turbidity in the Lucas test. The only 3∘ alcohol is (vi).

Which of the following alcohol will take minimum time in reaction with Lucas reagent?

Tertiary alcohols react quickly with Lucas reagent as proven by turbidity owing from the low solubility of the natural chloride in the watery mixture. Secondary alcohols react in five or so minutes (depends upon their dissolvability). primary alcohols don’t react with Lucas reagent at room temperature.

Which of the following will not give instant turbidity with Lucas reagent?

Explanation: Ethanol is a primary alcohol and does not give instant turbidity with Lucas Reagent. Methanol is also primary alcohol that does not give turbidity with Lucas Reagent. Isopropyl alcohol is secondary alcohol that gives turbidity with Lucas Reagent after 5 to 10 minutes.

Which gives immediate PPT with Lucas reagent?

Tertiary alcohols give turbidity immediately with Lucas reagent.

Why tertiary alcohol gives turbidity fastest with Lucas reagent?

Tertiary alcohols react immediately with Lucas reagent as evidenced by turbidity owing to the low solubility of the organic chloride in the aqueous mixture. Secondary alcohols react within five or so minutes (depending on their solubility).

Which of the following alcohol has the highest solubility?

Hence, glycerol has the highest solubility in water and so the correct option is D.

How many alcohol structural isomers are possible with the formula C5H12O will answer iodoform test?

Thus we can tell that 3-methyl butan-2-ol and pentan-2-ol give positive results for iodoform test. Hence only two isomeric alcohols of [{{text{C}}_5}{{text{H}}_{12}}{text{O}}] give positive result for iodoform test. Hence option C is correct. Which of the following compounds can exhibit tautomerism?

How many structural isomeric ethers are possible for C4H10O?

There are four isomeric alcohols of formula C4H10O . There are four isomeric alkyl bromides of formula C4H9Br .

How many isomers can C5H12 have?

Pentane – C5H12 has 3 isomers. They are Normal pentane, Iso pentane and Neo pentane.
