Question

Which of the following is the most stable alkene? (A)  R2C=CR2  (B)  RCH=CHR  (C)  RCH=CH2  (D)  CH2=CH2

We know that the greater the number of alley groups attached to double bonded carbon atoms, more stable is the alkene. Therefore most stable alkene is

R_{2} C = C R_{2}

Order of stability of alkenes is

C H_{2} = C H_{2} < RC H = C H_{2} < RC H

= C H R < R_{2} C = C R_{2}

Q. Which of the following is the most stable alkene?

$R_{2} C = C R_{2}$

$RC H = C H R$

$RC H = C H_{2}$

$C H_{2} = C H_{2}$

We know that the greater the number of alley groups attached to double bonded carbon atoms, more stable is the alkene. Therefore most stable alkene is $R_{2} C = C R_{2}$
Order of stability of alkenes is $C H_{2} = C H_{2} < RC H = C H_{2} < RC H$ $= C H R < R_{2} C = C R_{2}$

Q. Which of the following is the most stable alkene?

R2​C=CR2​

RCH=CHR

RCH=CH2​

CH2​=CH2​

We know that the greater the number of alley groups attached to double bonded carbon atoms, more stable is the alkene. Therefore most stable alkene is R2​C=CR2​ Order of stability of alkenes is CH2​=CH2​<RCH=CH2​<RCH =CHR<R2​C=CR2​

$R_{2} C = C R_{2}$

$RC H = C H R$

$RC H = C H_{2}$

$C H_{2} = C H_{2}$

We know that the greater the number of alley groups attached to double bonded carbon atoms, more stable is the alkene. Therefore most stable alkene is $R_{2} C = C R_{2}$
Order of stability of alkenes is $C H_{2} = C H_{2} < RC H = C H_{2} < RC H$ $= C H R < R_{2} C = C R_{2}$
