**Question:**Which of the following are used for heterogeneous catalytic hydrogenation?**Options:**- Ni- Pt- Wilkinson's catalyst**Explanation:**This question asks about catalysts used in the process of heterogeneous catalytic hydrogenation. In this process, a solid catalyst facilitates the addition of hydrogen to various substrates, usually unsaturated organic compounds. Common heterogeneous catalysts include:- **Ni (Nickel):** Often used in hydrogenation reactions due to its effectiveness and cost-efficiency.- **Pt (Platinum):** Known for its high catalytic activity, though it is more expensive than nickel.- **Wilkinson's catalyst:** This is actually a homogeneous catalyst, not used in heterogeneous catalysis.Thus, the options Ni and Pt are commonly used for heterogeneous catalytic hydrogenation.

Aromatic Compounds

Aromatic organic compound or aromatic system is an important class of hydrocarbons under the branch of organic chemistry. Aromatic compounds are also called arenas. The definition of aromatic organic compounds can be stated as a class of organic compounds with a planar cyclic ring of atoms bonded through alternated single and double bonds. Due to these alternating bonds, a peculiar feature termed as ‘resonance’, that is, delocalization of pi electrons or the electrons is shared within the atoms of the ring which are present in the aromatic compounds. The word ‘aromatic’ includes a Greek word ‘aroma’ which means smell, indicating that they were named as such due to the sweet odor they produce. Many well-known flavors such as vanilla, cinnamon, and few scents from flowers are extracted from aromatic compounds. Benzene with chemical formula C6H6 is a very common aromatic compound that contains six atoms of carbon held in the cyclic ring of alternate double bonds. It is also to be noted that not all aromatic compounds contain benzene ring. This can be explained by Huckel’s rule.
