1) 2-methylbutan-1-ol is heated with an excess of concentrated sulphuric acid (H2SO4) in order to cause an elimination reaction. a) Write an overall equation (using condensed formula) for this elimination reaction and name the reactants and products as pa...

2-methylbutan-1-ol is heated with an excess of concentrated sulphuric acid (H2SO4) in order to cause an elimination reaction: H3C-CH2-CH(CH3)-CH2OH + H2SO4 ==> H3C-CH2-C(CH3)=CH2 2-methylbutan-1-ol + concn H2SO4 ==> 2-methylbut-1-ene + water 1) Draw all o...

For part b: What is the identity of the product? What is the functional group that this product belongs to?

b) Draw the product of this reaction in displayed formula. c) Provide a ‘curly arrow’ mechanism (in displayed formula) for the formation of the product supported with an explanation.

1) ----H--H--CH3--H -----------------------------O ----------------H ----- CH2CH3 -----I----I----I----I -------------------------------II -------------------\ -------/ H - C - C - C - C - O - H -- +----- H - O - S -O -H ==> ---- C = C ------ + how -----I-...

2-methylbut-1-ene Option 1: -----H---H----------H -----I-----I----------/ H - C - C - C = C -----I----I----I------\ ----H---H---CH3- H Is the displayed formula for 2-methylbut-1-ene above right? Option 2 ----H---------H---H -----I----------I----I H - C =...

3) Provide a ‘curly arrow’ mechanism (in displayed formula) for the formation of the product supported with an explanation. Do I copy the displayed formula I did for part 1 and then add arrows? Where would I add the arrows if this is the case? What would...

------------H ------------| ------------O-H Is this the exact way water must always be drawn when asked for its displayed formula?

Do I write out the sulphuric acid like below: ------O -------II-------- OH - S - OH -------II-------- -------O

3) Step 1 -----------------CH3-------------------------------------CH3 -------------------I-------------------------------------------I CH3 - CH2 - CH - CH2 - OH ==> CH3 - CH2 - CH - CH2 - +OH --------------------------------- .. -------------------------...

The question means structural formula when it says displayed formula. Is my last post before your post right? Ignore the steps and arrows separating the steps. There is only a ^ arrow and not a down arrow so imagine that those are facing the opposite way.

This is an explanation I found online for when 2-methylpropan-1-ol is heated with concentrated sulphuric acid for an elimination reaction: Elimination in alcohols The dehydration is catalysed by strong acid, usually sulfuric or phosphoric acid, which prom...

It said online: The displayed formula and structural formula are fairly SIMILAR. The displayed formula represents the molecule by showing all of the atoms, and all of the bonds between those atoms. Bonds are represented by lines, with the number of lines...
