Key terms: reset 1,2-alkyl1,2-hydridee1e2 substitution a less stable carbocation can rearrange to a more stable carbocation by shift of a hydrogen atom or an alkyl group. these rearrangements are called and shifts, respectively. alcohols and ethers are both common products of . dehydration of secondary and tertiary alcohols occurs via an mechanism, while dehydration of primary alcohols follows an mechanism. the functional group known as contain a hydroxyl group (oh group) bonded to an sp³ hybridized carbon atom. alcohols undergo dehydration in the presence of strong acids, such as sulfuric acid (h2so4) or p-tolumenesulfonic acid (tsoh), to afford .

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
