<h2>Hydrophobic interactions. </h2>

Explanation:

  • Column chromatography is a technique used for separation in which a mixture having a mobile phase is caused to move in contact with the stationary phase.
  • The Stationary phase used is a solid and the mobile phase used is liquid.
  • There are interactions between the molecules of the analyte, stationary phase, and the various mobile phases like hydrogen bonding and dipole-dipole interactions.
  • The effect of these interactions is that the compound is retained for a longer time and as there are different interactions between stationary and mobile phases they are carried along with the mobile phases with varying degrees and the separation of the mixture is done.

All magnetic minerals will have the element iron in the chemical composition true or false
Margaret [11]

The statement is true. If a mineral lacks the presence of iron in it then it will be generally dimagnetic.  It means non iron minerals do not show magnetic property in general. There are some minerals like serpentine do show some magnetic susceptibility, however this is negligible as compared to iron minerals hence the ores with no magnetic are generally diamagnetic.

Draw a resonance structure, complete with all formal charges and lone (unshared) electron pairs, that shows the resonance intera
Angelina_Jolie [31]

Answer:

See explanation

Explanation:

The acetoxy group in ortho position in phenyl acetate does interact with the phenyl moiety in the molecule via resonance.

This detailed interaction of the  acetoxy group in ortho position in phenyl acetate with the phenyl moiety in the molecule via resonance is shown in the image attached.

This interaction is made possible because the oxygen atom of the acetoxy group has lone pairs of electrons that are suitably positioned to interact with the ring via resonance.
