Which one of the carbanions is the most stable-

Which one between the two CH_(3)COoverset(Theta)(C)H_(2) and CH_(3)COoverset(Theta)(C)HOCH_(3) is more stable and why?

What are the two planar conformations of 1,3-butadiene ? Which conformation is less stable and why ?

Decreasing order of stability of the given carbanions is (a) CH_3-C-=overset(Theta)C: (b) H-C-=overset(Theta)C: (c )CH_3-overset(Theta)overset(..)CH_2

Which of the following is less stable thermally-

Which of the following is less stable thermally-

What are the shapes of the free radicals overset(*)(C)H_(3),overset(*)(C)F_(3) and why?

Arrange the following anions in increasing order of stability and give reasons: CH_(2)=overset(Theta)(C)H,CH_(3)overset(Theta)(C)H_(2),CH-=overset(Theta)(C)

When any two sides and one of the opposite acute are given, under certain additional condition two triangle are possible. The case when two triangle are possible is called the ambiguous case. In fact when any two sides and the angle opposite to one of them are given either no triangle is possible or only one triangle is possible or two triangle are possible. In the ambiguous case, let a, b, and angleA are given and c_1,c_2 are two values of the third side c. Two different triangle are possible when
