(B) For b , same phenolic test can be done ...But other esterification is also possibility...
(C) Picric acid has a particular identification test ,
(D) Here , like the first one , phenolic test with FeCl3 gives violet color for 4-ethylphenol and no color for ethyl phenyl ether...
Answer: 5.84x10^4
Explanation: You start with (9.00x10^26 atoms)x(1 mol/ 6.022x10^23)x(39.10 g/1 mol)
<span>Abbreviated systematic numbering for Linolenic Acid is,
18:3, n-3
Explanation:
In above abbreviation
18 specifies number of carbon atoms in Linolenic Acid,
3 specifies the number of double bonds and
n-3 specifies the position of first double bond from methyl end. The structure of Linolenic Acid is as follow,</span>
Empirical formula = mol ratio
mol H = 9.42 x 10²⁴ : 6.02 x 10²³ = 15.648
mol N = 3/9 x 15.648 = 5.216
mass N = 5.216 x 14 g/mol =73.024 g
Answer:
None of the above
Explanation:
The (−OH) group on phenol can form hydrogen bonds, and the −CH3 group on toluene cannot.
Phenol has only one hydrogen on the −OH group available to form hydrogen bonds, so the hydrogen bond is stronger. In toluene, the hydrogen bond is spread over all three hydrogens on the methyl group, so the interaction is weaker overall.
Phenol has a higher molecular mass than toluene.
