Draw the addition product formed when one equivalent of hcl reacts with the following diene.
pashok25 [27]

Answer:

                    Major Product = 4-chloro-4-methylcyclohex-1-ene

Explanation:

                     Alkene are the class of organic compounds which contain one or more double bonds between two carbon atoms. Alkenes are considered most reactive among the unsaturated hydrocarbons and they undergo <em>addition reactions</em> due to high electron density around the double bonds.

                      In given question it is written that we are provided with one equivalent of HCl while, our compound contains two double bonds (diene) so in selected starting material the HCl will be added across (hydrohalogenation reaction) the substituted double bond because it will give a more stable carbocation (<u><em>tertiary carbocation</em></u>) during the reaction course. Hence, as shown in reaction scheme 4-chloro-4-methylcyclohex-1-ene will be the major product.

Which of the following is not equal to 485 L?
ELEN [110]

Answer:

4.85 * 10^4\ mL

Explanation:

Given

485 L

Required

Determine the measurement not equal to 485L

0.485\ kL

<em>From standard unit of conversion;</em>

1 KL = 1000 L

<em>Multiply both sides by 485</em>

485 * 1 KL = 485 * 1000 L

485KL = 485000L

<em>Divide both sides by 1000</em>

\frac{485KL}{1000} = \frac{485000L}{1000}

0.485KL = 485L  ---- This is equivalent

---------------------------------------------------------------------------------------------

4.85 * 10^4\ mL

<em>From standard unit of conversion;</em>

1000 mL = 1 L

<em>Multiply both sides by 485</em>

485 * 1000 mL = 1 L * 485

485000\ mL = 485\ L

Convert to standard form

4.85 * 10^5\ mL = 485\ L

Hence; 4.85 * 10^4\ mL is not equivalent to 485L

---------------------------------------------------------------------------------------------

48500 \ cL

<em>From standard unit of conversion;</em>

100 cL = 1 L

<em>Multiply both sides by 485</em>

485 * 100 cL = 1 L * 485

48500\ cL = 485\ L

Convert to standard form

4.85 * 10^4\ cL = 485\ L ---- This is equivalent

---------------------------------------------------------------------------------------------

4.85 * 10^8 \ μL

<em>From standard unit of conversion;</em>

1000000 μL = 1 L

<em>Multiply both sides by 485</em>

485 * 1000000uL  = 1 L * 485

485000000uL = 485\ L

Convert to standard form

4.85 * 10^8\ uL = 485\ L ---- This is equivalent

From the list of given options;

4.85 * 10^4\ mL is not equivalent to 485L
