Recognize physical and chemical properties of alcohols question what gives oxygen a partial negative charge and hydrogen a partial positive charge in the hydroxyl group -oh in an alcohol? select the correct answer below: o the oxygen atom has a significantly lower electronegativity than the hydrogen atom. o the oxygen atom has a significantly higher electronegativity than the hydrogen atom. o the oxygen atom and hydrogen atom both have approximately the same electronegativity. o an extra electron is donated from the carbon attached to the hydroxyl group. feedback more instruction submit content attribution

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
