Elimination Reaction for some alcohols and alkyl halides will result in different alkene products, and Saytzeff or Zaitsev Rule is used to determine the major product. <br /> <br />Saytzeff or Zaitsev Rule states that the more substituted alkene will be the major product. <br /> <br />So by looking at the number of alkyl groups attached to the alkene, the degree of substitution and hence major and minor products can be determined. <br /> <br />For a step-by-step guide to predict the major product using Saytzeff Rule, check out this video lesson now! <br /> <br />Maverick Puah the Chemistry Guru is a top A Level Chemistry Tutor in Singapore.
