The question is fill in the blank:


Diels Alder reactions are __________.


I've already tried the following: -green reaction/ green

-pericyclic / pericyclic reaction -nucleophilic acyl substitution/ nucleophilic acyl substitution cascade reaction - concerted mechanism -sterospecific -reversible -spontaneous -bicyclic / bicyclic compound -cycloaddition -cyclohexane -indispensable / indispensable reaction -biosynthetic -natural -tandem -reactive -nonspontaneous -unique

-conjugated

2,5,6-trimethyldecane

1. Draw and name 4 hydrocarbon molecules. One must be an alkane, one must be an alkene, one alkyne and one benzene. Each molecule must have an alkyl group of a different length. Two of the molecules must have multiple alkyl groups.





2. Draw (expanded structural diagrams (show hydrogens))and name one molecule from each (oxygen and nitrogen containing) family that we discussed in this course (8 molecules in total).


Each molecule must have;


a double or triple bond

an alkyl branch

a phenyl or halide branch

Two of the molecules must have


an 'iso' alkyl branch

at least two double or triple bonds

can I know what is the classes of compound for the isomers?

Name



CH5

|

CH3-CH2-CH-CH3

|

CH3

Draw eight possible constitutional isomers containing three membered cyclic ring with molecular formula C5H10O. Identify the classes of compounds for the isomers.

Calculate the mole efficiency of NAOH when 4 grams of NaOH is soluble in 90 grams of water.

2,3 dibromo buten reaction with zinc in the presence of d clho7 it gives buten

which is more reactive towards electrophillic substitution reaction and why?

a)C6H5OH(Phenol)

b)C6H5CH2OH

Assertion-Allyl carbanion is more stable than CH2NO2


Reason-In CH2NO2 only -I effect of NO2 is there while in allyl carbanion resonance is present


Why is the assertion wrong?Isn't the reason right?When NO2 is attached with single bond to CH2 it should show only -I effect.
