How to place dotfill and droppoints on the same line

Question

I have these codes

\documentclass[a4paper]{exam}
\usepackage{chemfig}
\usepackage[version=4,arrows=pgf-filled]{mhchem}
\usepackage{chemmacros}
\begin{document}
\pointsdroppedatright
\setlength\dottedlinefillheight{1cm}
\begin{questions}
\question
Complete the following equations and write the I.U.P.A.C names of the main 
organic product in each case. 
\begin{parts}
\part[01 mark] 
\ce{CH3CH=CH2 ->[\ce{MnO4 \mch[] / OH \mch[]}]} 
\fillwithdottedlines{1cm} \droppoints 
Name of product \fillwithdottedlines{1cm} \droppoints 
\end{parts}
\end{questions}
\end{document}

When compiled, it gives the image below.

What I need is given below.

Thanks in advance

Answer 1

The \fillwithdottedlines command inserts dotted lines BELOW the text.

Could be like that?

\usepackage{chemfig}
\usepackage[version=4,arrows=pgf-filled]{mhchem}
\usepackage{chemmacros}

            \ce{CH3CH=CH2 ->[\ce{MnO^{-}_{4} / OH-}]} \dotfill
            
            Name of product \dotfill
        \end{parts}
    \end{questions}
