Draw the structure of a compound of molecular formula c4h8o that has a signal in its 13c nmr spectrum at ≥ 160 ppm. then draw the structure of an isomer with no rings of molecular formula c4h8o that has all of its 13c nmr signals at < 160 ppm.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

um i think it might be a car?
