Van der waals forces < hydrogen bonding forces < Crystal lattice forces.
Explanation:
Hydrogen bonds are very strong intermolecular forces. They are a special dipole-dipole bonds formed by the attraction between hydrogen atom of one molecule and an electronegative atom of another molecule.
- Hydrogen bonds are stronger than van der waals forces.
- Van der waals forces are weak attractions joining non-polar and polar molecules together.
- Hydrogen bonds are more effective in binding molecules together.
- Crystal forces are found in solids and are strong electrostatic forces of attraction between oppositely charged ions

Answer:
None of these
Explanation:
Friedel–Craft reaction is a reaction involves the attachment of substituents to the benzene ring.
Mechanism of the reaction of methylbenzene with 1-chlorodecane in the presence of ether and aluminum chloride :
Step -1 : Generation of stable carbocation.
Aluminium chloride acts as Lewis acid which removes the chloride ion from the alkyl halide forming carbocation. The primary carbocation thus formed gets rearranged to secondary primary carbocation which is more stable due to hyperconjugation.
Step-2: Attack of the ring to the carbocation
The pi electrons of the ring behave as a nucleophile and attacks the carbocation. Since, the group attached on the benzene is methyl (+R effect) , the attack is from the ortho and the para positions. Para product is more stable due to less steric hinderance.
The product formed is shown in mechanism does not mention in any of the options.
So, None of these is the answer
Tonga Trench is convergent.
- In the western Pacific Ocean, there is a trench known as the Tonga Trench. It is the second-deepest trench on Earth after the Mariana Trench and the deepest in the Southern Hemisphere.
- The Tonga Trench was created millions of years ago by a process known as subduction, in which two tectonic plates collide and push one under the other.
- The Tonga Trench is 850 miles long and typically reaches depths of 20,000 feet.
- From the southwest corner of the Kermadec Plate to the northwest point of the Tonga Plate, there is a convergent plate boundary known as the Kermadec-Tonga subduction zone.
- The Tonga Trench's Horizon Deep, located at 23.25833°S 174.726667°W, is its deepest point.
- There are numerous volcanoes in the Tonga Trench, both active and dormant, and it is prone to earthquakes and tsunamis.

Answer:
nonpolar
Explanation:
A nonpolar solvent has the highest solubility with a <u>nonpolar</u> solute.
Cells and microorganisms are extremely complex
