Chapter name on single page

Question

I was wondering could anybody help me out, I would like to have one chapter heading alone in the centre of a page. All the other chapters will stay as normal, with the text on the same page.

\documentclass[a4paper, 12pt, oneside]{book}
\usepackage[a4paper,top=40mm, bottom=40mm, left=40mm, right=30mm]{geometry}
\usepackage[english]{babel}

\begin{document}

%preambles

\chapter{introduction}
some text here
\section{name}
some text here

\chapter{background}
some text here
\section{name}
some text here

\chapter*{discussion}% I would like for this chapter heading to be centred on a single page and the section to go to next page
some text here
\section{name}
some text here

\end{document}

Answer 1

I think the following achieves what you're looking for: Replace the instruction

\chapter*{discussion}

with

\part*{discussion}
\markboth{}{}

This will put the word "discussion" in the middle of the page, centered both horizontally and vertically.

After that, continue with \chapter and \section as usual.

A full MWE:

\documentclass[a4paper, 12pt, oneside]{book}
\usepackage[vmargin=40mm, left=40mm, right=30mm]{geometry}
\usepackage[english]{babel}
\usepackage{lipsum}

\begin{document}

%preambles

\chapter{introduction}
some text here
\section{name}
\lipsum[1-5]

\chapter{background}
some text here
\section{name}
\lipsum[1-5]

\part*{discussion}
%\markboth{}{}


\chapter{details}
some text here
\section{whatever}
\lipsum[1-5]

\end{document}
