Isomerism that arises out of the difference in spatial arrangement of atoms or groups about the doubly bonded carbon atoms are called?
Structural Isomerism
Stereoisomerism
Geometrical Isomerism
Optical Isomerism
Which among the following does not exhibit geometric isomerism?
1-hexene
2-hexene
3-hexene
4-hexene
Which statement best defines chain isomerism?
Existance of chemical compounds with same molecular formula
Different ways the same number of carbons are connected which is either straight or branched
Have mirror image of each other
Similar chemical properties with different physical properties such as solubility
How to determine that a molecule exhibit cis-trans isomerism?
Restricted rotation in a carbon-carbon single bond of alkenes
Each carbon of a site of restricted rotation has 2 different atoms or groups attached to it
Exist in cyclic compouds only
Similar chemical properties
Two optical isomers have the same
Empirical formula
Structural formula
Molecular formula
Which of the following molecules exhibit geometrical isomerism?
CH2=CHCH3
C6H5CH=CHC6H5
(CH3)2C=CHCH3
CH3CH2N=OH
Butan-1-ol and Butan-2-ol exhibit (a) isomerism
Isomerism exhibited by acetic acid and methyl formate is
position
chain
functional
metamerism
Define chirality centre
also known as chiral carbon
a type of enantiomer
a sp3 hybridised carbon with four different groups or atoms attached to it
optically active compounds
Can enantiomer rotates plane-polarised light?
Yes in all situations
No because it is optically active
Yes but it can only rotate the polarised light in opposite direction
No due to its restricted rotation of carbon-carbon double bond
Is it true that enantiomer have the same physical and chemical properties?
Yes
False
