I'm not sure how to do it via an iDevice but it's possible via a laptop/desktop.
With Chrome you need to launch Bookmark Manager. Once in Bookmark Manager click on Organize and Export Bookmarks to HTML. Save this file, but keep it somewhere accessible. Now open Safari and click on File then select Import Bookmarks and select your HTML file. Now Safari should do it's thing
On your iDevice your Bookmarks (as long as your iTunes account is linked to the same as the computer) should appear.
