E2 for tertiary halides, E1 for primary and secondary halides- b. E1- c. E1 for tertiary halides, E2 for primary and secondary halides- d. E2_Selected Option: d_These questions pertain to organic chemistry, specifically focusing on the stability of alkenes and mechanisms of elimination reactions involving alkyl halides. Understanding the properties of each alkene, such as the degree of substitution and the Zaitsev rule, is crucial in determining stability. Similarly, knowledge of E1 and E2 mechanisms helps predict reaction outcomes based on the structure of the alkyl halide and the strength of the base used.

Concept explainers

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
