Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

At times when same compound is represented in two different forms that might lead to believing that the representations are of two different compounds; these two different representations are called homomers. A homologue is a compound belonging to a series of compounds differing from each other by a repeating unit, such as a methylene bridge −CH ₂−. methane ethane propane etc. In conformations of butane along C2-C3 bond,when in newmann projections we represent two methyl groups at 60. position , conformation is gauche. Skew conformations are infinite conformations in between the specific ones formed due to rotation along the bond but they are not anti,staggered, or gauche.
