Which statement describes the magnetic effect of a bar magnet

Chemistry
1 answer:
zepelin [54]3 years ago
7 0

Answer:

The field is most concentrated at the poles of the magnet

Explanation:

Magnetic fields are strongest at the poles of the magnet. At this place, they are most concentrated and have the biggest force.

A magnetic effect is produced in the vicinity of a magnetic body usually a bar magnet.

Magnetic fields are strongest in the region of the north and south pole. At every other points they are weaker.

25. 22 the reaction of phenylmagnesium bromide with methyl benzoate followed by acidification produces triphenylcarbinol. what a
ExtremeBDS [4]

Triphenylcarbinol( or triphenylmethanol) gets its phenyl groups from phenylmagnesium bromide.

Synthesis of triphenylcarbinol:

A typical laboratory experiment for demonstrating the Grignard reaction is the synthesis of triphenylmethanol using methyl benzoate, benzophenone, and phenylmagnesium bromide. Diethyl carbonate is a possible starting material.

Characteristics:

  • An organic substance is a triphenylmethanol. It is a white, crystalline substance that dissolves well in alcohol, diethyl ether, and benzene but not in water or petroleum ether. Due to the creation of a persistent "trityl" carbocation, it generates a bright yellow hue in very acidic solutions. Important dyes include several triphenylmethanol derivatives.
  • Triphenylmethanol has a core tetrahedral carbon atom, three phenyls (Ph) rings, and an alcohol group attached to it. With lengths of around 1.47Å for all three C-Ph bonds and 1.42Å for the C-O link, these connections are characteristic of sp3-sp2 carbon-carbon bonds.
  • Three neighboring phenyl groups give off specific qualities that are reflected in the alcohol's reactivity.
