for alkane series the formula is
C n H 2n+2
so the formula of b utane is
C 4 H 10
The correct answer is option C.C4H10
What is straight chain isomerism?
These isomers occur because they can branch off at the carbon chain. For example, butane has two isomers, C4H10. One of them has a "linear" carbon atom and the other has a branched chain.
Butane is a 4-carbon alkane, so its molecular formula is C4H10. There are two isomers. n-Butane and isobutane. Here, n-butane is a linear compound with four carbon atoms connected by a single covalent bond.
\Compounds with the same molecular formula but different arrangements of carbon atoms in the straight or branched chain are called chain isomers. n-Butane and isobutane are chain isomers because they have different carbon atom arrangements

The chemical equation below shows the decomposition of nitrogen triiodide (NI3) into nitrogen (N2) and iodine (I2). 2NI3 Right arrow. N2 3I2 The molar mass of NI3 is 394. 71 g/mol. How many moles of I2 will form 3. 58 g of NI3? 0. 00907 moles 0. 00940 moles 0. 0136 moles 0. 0212 moles.
The moles of I₂ will form from the decomposition of 3.58g of NI₃ is 0.0136 moles.
How we calculate moles?Moles of any substance will be calculated as:
n = W/M, where
W = required mass
M = molar mass
Given chemical reaction is:
2NI₃ → N₂ + 3I₂
Moles of 3.58g of NI₃ will be calculated as:
n = 3.58g / 394. 71 g/mol = 0.009 moles
From the stoichiometry of the solution, it is clear that:
2 moles of NI₃ = produce 3 moles of I₂
0.009 moles of NI₃ = produce 3/2×0.009=0.0136 moles of I₂
Hence, option (3) is correct i.e. 0.0136 moles.

Answer:
The formation of double and triple bonds is not as widespread among the atoms of the periodic table as one might expect. At least one of the atoms involved in a multiple bond is almost always C, N, or O, and in most cases both atoms are members of this trio
Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.
