WHAT IS THE CONDENSED STRUCTURAL FORMULA OF 2,3-DIMETHYL-2-BUTENE

You don't stand much chance of an answer when you piggy back onto another question. You should go to the top of the page, click on Post a new question, and post the new question.

I would write this as

(CH3)2CH=CH(CH3)2

A chemist is producing copper(II) chloride using the following reaction:

Cu(s) + Cl2(g) --> CuCl2(s)
In one reaction, the chemist uses 15.0 g of copper metal and 10.0 g of chlorine gas as reactants. When the reaction reaches completion, 16.0 g of copper(II) chloride has been produced. What was the percent yield of the reaction?

The condensed structural formula represents the structure of a molecule in an abbreviated form. In the case of 2,3-dimethyl-2-butene, let's break down the name to understand its structure.

First, we have "2,3-dimethyl," which means that there are two methyl groups (CH3) attached to the 2nd and 3rd carbon atoms in the main chain.

Next, we have "2-butene," which implies that there is a butene chain with a double bond (denoted by "-ene") starting from the 2nd carbon atom.

To write the condensed structural formula, we can start from the main chain of butene, which has four carbon atoms. We place the methyl groups on the appropriate carbon positions: the 2nd and 3rd carbon atoms.

Therefore, the condensed structural formula of 2,3-dimethyl-2-butene is:

CH3 - CH = C(CH3)2 - CH3

In this formula, "-" represents a single bond, "=" represents a double bond, and the parentheses "( )" enclose the methyl groups attached to the carbon atom.
