Answer:
50km
Explanation:
70km - 20km = 50 kilometers
Answer: 410 nm
Explanation: Energy of a photon is E = hf = hc/λ. The smaller wavelength λ, the greater energy
Chemical Bond
because they are chemically bonding
Answer:
(Z)-4-methyl-2-pentene
Explanation:
Hydrogenation is a syn addition. This implies that the hydrogen atoms add to the same face of the multiple bond.
Hence, if we have the alkyne, 4-methyl-2-pentyne which reacts with excess hydrogen in the presence of a platinum catalyst, we obtain (Z)-4-methyl-2-pentene since the hydrogen atoms add on the same side of the multiple bond.
