If a non-cyclic alkane shows a molecular ion peak at m/z 3.80 × 102, what is the chemical formula?
soldier1979 [14.2K]
The General Equation of Alkane is as follow,

                                              CnH₂n₊₂          ------- (1)
As m/z = 380
So,
                                              CnH₂n₊₂  =  380
Or,
                                              12n+ 1₂n₊₂  =  380

                                              12n+ ₂n ₊ ₂  =  380

                                              14n ₊ ₂  =  380

                                                   14n  =  380 - 2

                                                   14n  =  378

                                                       n  =  378 / 14

                                                       n  =  27
Now, putting value of n in eq. 1

                                              C₂₇H₍₂₇ₓ₂₎₊₂

                                                  C₂₇H₅₆
Result:
           n  =  C  =  27

           y  =  H  =  56

How does the number of protons compare to the number of<br> electrons in a canton
Tema [17]

Answer: The number of protons in cation is more than the number of electrons

Explanation:

cations are positive ions that means that they lose electrons to be stable nd have electron configuration (atomic number ) equivalent to the preceding noble gas

as : sodium 11 , it loses on electron to be stable and its electron configuration is equivalent to neon 10

so ,the number of protons in cation is more than the number of electrons

i hope it helps!
