Answer:
Option d.
Explanation:
Ketones contain a carbonyl groups as a functional group, which is a carbon bonded to oxygen with a double bond. In a ketone, the carbon is always bonded to two carbon atoms:
R-C(=O)-R'
The carbon in the carbonyl group has a hybridization sp2 (3 hybrid orbitals with an unhybridized p orbital), where two of the orbitals form sigma (σ) bonds with the other two carbons (R-C-R') and the other hybrid orbital form a sigma bond with the oxygen (C-O). The unhybridized p orbital on the carbon atom is used to form a pi (π) bond with the oxygen, thus forming the double bond (C=O).
The bond of a carbonyl group is polar, because of the difference of the electronegativity between the carbon atom and the oxygen atom.
Hence, from all of the above we can discard the option a, (the carbonyl groups exhibits sp2 hybridization), the option b (carbon-oxygen bond is a bond polar) and the option c (the group must always be in the middle of a carbon chain, the groups that are always in the end, are a aldehyde groups).
Therefore, the correct option is d, the functional group of this type of compound must always be in the middle of a carbon chain.
I hope it helps you!
Answer:
d. The functional group of this type of compound must always be in the middle of a carbon chain.

Answer:
The three isomers having the molecular formula are drawn in the figure below.
Explanation:
c) potassium, K(s)
b) manganese, Mn(s)
d) boron, B(s)
Answer:
The molar mass of:
Helium = 4.00 g/mol
Potassium = 39.0983 g/mol
Manganese = 54.94 g/mol.
Boron = 10.81 g / mol
Explanation:
Helium = 4.00 g/mol
Potassium = 39.0983 g/mol
Manganese = 54.94 g/mol.
Boron = 10.81 g / mol
Answer:
Rate of reaction will be half of it's initial value
Explanation:
For the given reaction, the rate law is -
Where k is rate constant, [1-iodo-2-methylbutane] is concentration of 1-iodo-2-methylbutane and is concentration of
Here nucleophile is the ion
Initiallly,
When concentration of is halved then-
So rate of reaction will be half of it's initial value
Answer:
Explanation:
Hello,
In this case, for the given chemical reaction, we can notice there is a 4:2 molar ratio between the burned moles of gallium and the yielded moles of gallium sulfide, therefore, we compute them as shown below:
Then, by using the molar mass of gallium sulfide (235.64 g/mol), we directly compute the grams:
