<span>I would propose the word trigonal pyramidal or pyramidal . This is because the bond angle in ammonia ( also known as NH3) is about 107 degrees. Also please note that the number of bonding pairs of electrons in ammonia (NH3) is 3 and the Number of lone pairs of electrons in ammonia(NH3) is 1. Finally it has 8 valence electrons (5 + 3x1 = 8).</span>
Answer:
Wave Height: the higher the height, the higher the amplitude, and vice versa
wavelength: the shorter the wavelength, the higher the frequency, and vice versa
velocity: the higher velocity, the higher the frequency (and variable amplitude)
Answer: 1/2L
Explanation:
Volume and pressure are changed, so use Boyle's law.
P1V1=P2V2
Convert 303.9kpa to atm by mutiplying by (1/101.3)=3atm
Plug in:
1.5(1)=3(V2)
V2=1/2 L
This makes sense since volume and pressure are inversely proportional. The pressure is increased, so the volume must decrease.
I believe it’s a. hope this helps
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
