Answer:
A,D,E,F
Explanation:
A.Ketones generally have lower boiling points in relation to alcohols because of the intermolecular hydrogen bonds.
D.Aldehyde group is known for this C=O group in which Carbon has a double bond with Oxygen.
E. Aldehydes and Ketones can’t hydrogen bond with each other but they can hydrogen bond with water
F. Formaldehyde used in the laboratory for preservation is a liquid at room temperature while propanol which has more carbon is gaseous
B is wrong because as the Carbon increases the solubility in water decreases
C is wrong because 2-butanol has a bp of 100 degree celsius while butanal has a bp of around 74.
Answer:
a.Phenols have the ability to spread out the negative charge that forms.
Explanation:
This happens because of the aromatic ring the phenols have. When loosing the proton, the anion formed have different resonance isomers due to the double bonds in the aromatic ring. This resonance makes the anion more stable and prevents the reaction going backwards.
On the other hand, regular alcohol doesn't have resonace and the reaction of loosing the proton goes leftward and righward: is in equilibrium.
That equilibrium decreases the acidity of the alcohol.
The IUPAC rules are
a) Find out the longest chain of carbon in the given organic compound
b) We will name the longest chain.
c) We will identify the main functional group and will assign a suffix to the compound.
d) We will number the carbons in the longest chain selected so that the attached groups attain lowest numeral as substituent
e) We will name the side groups or chains.
