I really need help with this chem question. Can anybody answer it with an explanation for the answer? Thanks.

C. Because you eliminate "spectator ions" or ions that are repeated and you can only do that to aqueous. So, Ca +2 and 2I -1 are the only ones you can remove for net ionic.

Design a synthesis of acetophenone from benzene or toluene. 1275q Part 1 out of 5 Choose the best option for the nucleophile pre

Trava [24]

Answer:

A Fridiel craft catalyst will convert benzene to acetophenone.

Permanganate catalyst can be used to convert toluene to acetophenone.

Explanation:

Benzene can be reduced to acetophenone by the addition of anhydrous aluminium chloride, AlCl₃

The mechanism is as follows:

Benzene + Acetyl choloride → acetophenone

To convert toluene to acetophenone, the following steps are necessary:

Oxidation of Toluene to Benzoic acid.

This is done by refluxing toluene with alkaline potassium permanganate (KMnO₄+ Na₂CO₃).

Benzoic acid is converted to Benzoyl chloride by treating with thioyl chloride and heating at about 80 ⁰C.

Benzoyl chloride is treated with methyl lithium to form Acetophenone.

The partial Lewis structure that follows is for a hydrocarbon molecule. In the full Lewis structure, each carbon atom satisfies

ahrayia [7]

Answer:

$C-C> C=C> C\equiv C$

So, 2 $>$ 1 $>$ 3

Explanation:

Carbon is a non-metal and has 6 electrons. In the excited state, it contains 4 electrons in its outermost shell and so 4 electrons take place in covalent bond formation. In a molecule , 2 carbon atoms can be bound by a single bond, the double bond and by a triple bond. Since the bond length of $C\equiv C$ is 120 pm, the bond length of $C=C$ is 134 pm and the bond length of $C-C$ is 154 pm. Thus in the given compound, $C= C-C\equiv C$ , in which $C= C$ is labeled as 1, $C-C$ is labeled as 2 and $C\equiv C$ is labeled as 3. So the bond length of carbon-carbon bonds in the molecule, in decreasing order is $2 > 1 >3$ .
