Draw a mechanism for the first step of the reaction between methyllithium (CH3Li) and acetone. Then answer the two multiple choi
ce questions underneath your mechanism.
1 answer:
Answer:
See the attached image
Explanation:
The first step is the production of the <u>carboanion</u> in the compound. We will get the <u>negative charge</u> on the methyl group and the <u>positive charge</u> in the Li atom.
Then the carboanion can <u>attack the acetone</u>. The double bond of the oxo group would <u>delocalized</u> upon the oxygen, generating a positive charge in the carbon that can be attacked by the carboanion formaiting a <u>new C-C bond</u>.

Explanation :
Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.
Ionic compound are usually formed when a metal reacts with a non-metal.
The nomenclature of ionic compounds is given by:
1. Positive ion is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
3. In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.
(a)
is an ionic compound because titanium element is a metal and oxygen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on tin is (+4) and the the charge on oxygen is (-2). Thus, the name for is titanium(IV) oxide.
(b)
is an ionic compound because barium element is a metal and chlorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on barium is (+2) and the the charge on chlorine is (-1). Thus, the name for is barium chloride.
(c)
is an ionic compound because copper element is a metal and chlorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on copper is (+3) and the the charge on chlorine is (-1). Thus, the name for is copper(III) chloride.
(d)
is an ionic compound because potassium element is a metal and iodine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on potassium is (+1) and the the charge on iodine is (-1). Thus, the name for is potassium iodide.
(e)
is an ionic compound because strontium element is a metal and chlorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on strontium is (+2) and the the charge on chlorine is (-1). Thus, the name for is strontium chloride.
(f)
is an ionic compound because copper element is a metal and bromine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on copper is (+2) and the the charge on bromine is (-1). Thus, the name for is copper(II) bromide.
