Answer:
2
Explanation:
The compound H2CCH2 has the condensed formula C2H4. The name of the compound is ethene. The compound is unsaturated, that is, it contains multiple bonds. The compound has a formula which fits into the general molecular formulae of alkenes (olefins) which his CnH2n.
Olefins have a double bonds between the carbon atoms. That is , the two carbon atoms in Olefins are connected via a double covalent bond. This now implies that the two carbon atoms in ethene (C2H4) are connected by two covalent bonds in the lewis structure of the molecule as is common for Olefins.
Tin(Sn)
Explanation:
The element with similar chemical properties with lead (Pb) from the given options is tin(Sn).
- Chemical properties of an element depends on the number of valence electrons they have.
- Element in the same group on the periodic table have similar chemical properties because the number of valence electrons are the same.
- Tin and lead belong to group iv on the periodic table.
- Other elements in this group are carbon, silicon, germanium
- All these elements have similar chemical properties.

Explanation:
Starting from acetylene, we can react the substrate with methyl iodide in the presence of sodamide and ammonia. We then obtain propyne which then undergoes a similar reaction using butyl iodide to yield 2-heptyne.
This may now be reduced using hydrogen and platinum to yield heptane. Heptane is chlorinated in the presence of light to yield a mixture of products of which 1-chloroheptane is one.
