Answer:iliocostalis group
Explanation:
It's located on the back of the human body and here are some of what this group do;
• Acting together, muscles of each consistuent region extend and maintain erect posture of vertebral column in their respective region.
• Acting singly, laterally flex vertebral column in their region.
Proton is a nucleon with a positive charge in the center of the atom, neutrons are nucleons which are also in the nucleus, or center of the atom and have no charge. Both protons and neutrons have a mass of 1 atomic mass unit (amu). Electrons are negatively charged and orbit the nucleus and have a mass of 1/1836 amu which is much less then the nucleons
The mechanism is as suggested
1) Protonation of alcohol
2) removal of water molecule to give carbocation
3) hydride shift to give more stable carbocation [rearrangement]
4) the stability of carbocation due to resonance
5) removal of proton and formation 1-phenyl-1-propanone.
This is Pinacole pinacolone rearrangement
Thus the reaction can be depicted as
