Link to external site if post id

Hi there

I am currently displaying a list of posts within a category id using get_posts. Each post is displayed in an <li> and links to the_permalink. This works fine but I want one of the posts to link to an external site based on the post id which is 17. I’ve had a go at this but can’t seem to work it out and am new to this. Any help much appreciated!

<?php while (have_posts()) : the_post(); ?>

  <?php the_content(); ?>

<?php endwhile; ?>  

<ul>
	<?php

		$args = array(
			'posts_per_page' => 5,
			'category' => 2
		);

		$myposts = get_posts( $args );

		foreach ( $myposts as $post ) : setup_postdata( $post ); ?>

		<!-- if the post id = 17 create a url link to google
		otherwise make the link go to the permalink -->
		<?php $my_id = get_the_ID(17); ?>
		<?php if( $my_id ) { ?>
		<li>
			<a href="https://www.google.com"><?php the_title(); ?></a>
		</li>
		<?php } else { ?>
		<li>
			<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
		</li>
		<?php } ?>

		<?php endforeach; wp_reset_postdata(); ?>

</ul>
